How do you find the mass of an atom of gold?
From our discussion of molar mass and the mole, we know that 6.022 times 10 to the 23rd atoms of gold will have a mass of 197 grams. We can set this relationship equal to 𝑥 atoms per 15.81 grams. Solving for 𝑥 will give us the number of gold atoms in the quantity of gold the prospector panned.
What is mass of gold?
196.96657 uGold / Atomic mass
How do you find the mass of moles?
The amount of grams in a mole depends on the substance you have. To work it out, find the atomic or molecular mass of your substance and multiply it by the number of moles you have. For one mole, the atomic or molecular mass will be the same as the weight.
How do you find the mass number?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
How do u calculate mass?
Mass is always constant for a body. One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.
What is the mass of a mole?
The mole is related to the mass of an element in the following way: one mole of carbon-12 atoms has 6.02214076 × 1023 atoms and a mass of 12 grams.

How do you convert moles to mass?
Multiply the molecular weight by the number of moles for the substance. The molecular weight is the number of grams per mole for the substance and gives the conversion factor for moles to grams for that particular substance. So, one mole of water has a mass of 18.02 grams (1 mol H2O x 18.02 g/mol = 18.02 g).

Which is the correct way of converting moles to mass?
Multiply the molecular weight by the number of moles for the substance. The molecular weight is the number of grams per mole for the substance and gives the conversion factor for moles to grams for that particular substance. So, one mole of water has a mass of 18.02 grams (1 mol H2O x 18.02 g/mol = 18.02 g).
