If you are taking Chemistry’s test on school, job or quizzes, you will surely find the questions about Atoms. The example question about atoms would be ‘How many atoms or molecules are present in 1.0 mol of Au?’, ‘How do you find moles of gold atoms?’, etc.
But, how if you find the answer but don’t know what the question is from the answer you found? You shouldn’t worry, since we will show the question of the answers you found. So, let’s dive into our post to find the questions!
A Mole of Gold Atoms, Because Gold has a Greater Molar Mass Than Silver, What Is the Question of This Answer?
We finally found the questions for the answers of ‘A Mole of Gold Atoms, Because Gold has a Greater Molar Mass Than Silver’ from Quizlet.com. Here’s it!
- Question: Which has a greater mass, a mole of silver atoms or a mole of gold atoms?
- Answer: A Mole of Gold Atoms, Because Gold has a Greater Molar Mass Than Silver
So, the question for the answers of ‘A Mole of Gold Atoms, Because Gold has a Greater Molar Mass Than Silver’ is ‘Which has a greater mass, a mole of silver atoms or a mole of gold atoms?’
Explanation:
Well, it is true that a mole of gold atoms has a greater mass, since gold has a greater molar mass than silver. It is known that a mole is the number of particles such as molecules or atoms which are equal to exactly 12.000 g of carbon-12. Just like a mole represents a set number of atoms or molecules, a dozen represents a set of 12 objects.
There are 6.022 x 1023 atoms in one mole of gold. Well, a mole will have the same number of units whether you are trying to count atoms or molecules. The number used here is Avogadro’s number for the scientist who determined there were 6.022 x 1023 carbon atoms in a 12-gram sample of carbon-12.
About Gold Atom
Gold Atom is a soft metal with a characteristic yellow colour that is chemically unreactive, even though it will dissolve in aqua regia. In fact, most mined gold will be stored as bullion and is also used extensively in jewellery, either as an alloy or in its pure form.
Well, the term ‘carat’ refers to the amount of gold present in an alloy. The 24-carat is pure gold, but it is very soft, while 18-and 9-carat gold alloys are generally used since they are more durable.
This metal can also be used for coinage that has been used as standard for monetary systems in some countries. Furthermore, gold can be beaten into very thin sheets that can be used in art for decoration and as architectural ornament.
The electroplating will be used to cover another metal with a very thin layer of gold that can be used in gears for watches, cheap jewellery, artificial limb joints and electrical connectors. Well, that is very ideal to protect electrical copper components since it conducts electricity well and does not corrode. The thin gold wires can be used inside computer chips to create circuits.
It is known that dentists sometimes use gold alloys in fillings that are further used to treat some cases of arthritis. Gold nanoparticles will be increasingly being used as industrial catalyst and vinyl acetate that is used to create PVA is created using a gold catalyst.
Reportedly, gold is non-toxic and has no known biological role that is one of the few elements to occur in a natural state. Gold is commonly found in veins and alluvial deposits and approximately 1500 tonnes of gold are mined each year. Around two-thirds of this comes from South Africa and most of the rest of Russia.
For more information, a sweater contains roughly 4 grams of gold in 1,000,000 tonnes of water. This is a huge amount of gold that is stored in the oceans.

The related questions about Chemistry are available in a number of websites. In this post, however, we will show you the related questions about Chemistry that we find from Quizlet.com. Here are they:
Questions:
- Why is the mole an important unit to chemists?
- How is a mole similar to a dozen?
- What is the numerical value of Avogadro’s number?
- What is molar mass?
- Which contains more atoms, a mole of silver atoms or a mole of gold atoms?
- Discuss the relationship that exists between the mole, molar mass, and Avogadro’s number!
- Explain the difference between atomic mass (amu) and molar mass (g)!
- If you divide the molar mass of an element by Avogadro’s number, what is the meaning of the quotient?
- List 3 conversion factors used in molar conversions!
- Drop the numbers after the __________ place!
Answers:
- The mole is a convenient method for chemists to use to count the number of atoms in a substance
- They both represent a specific amount of a substance
- 6.02 x 10^23 (1 mole)
- The mass in grams of one mole of any pure substance
- Neither, 1 mole of each contains 6.02 x 10^23 atoms
- Molar mass = the mass in grams of 1 mole of any substance
Avogadro’s number = the # of particles in 1 mole
The mass of 6.02 x 10^23 particles = the molar mass of a substance - Atomic mass is the mass of an individual particle, while molar mass is the mass of 1 mole of particles
- It is the number of molecules in that element
- grams to moles
moles to grams
moles to atoms - Hundredths
