How do you convert molar mass into moles?

Answer 1

To convert moles of a substance into grams you first need to figure out its molecular mass. Then you can use this equation:

grams(g)=moles(n) X molecular mass

For example, 1 mole of Carbon (which has a molecular mass of 12) has a mass of 12 grams.

Answer 2

To convert molar mass to moles, use the formula: moles = mass (g) / molar mass (g/mol). Simply divide the mass (in grams) of the substance by its molar mass (in grams per mole) to find the number of moles.

Answer 3

You use the Atomic Mass, which is found on the Periodic Table. One mole of an element has the mass reported on the periodic table, usually under the symbol of that element. If you have a compound, add the masses of each of its components. For example, if you have 1 mole of C2H6, its mass would be equal to 2(12.01g/mol C)+6(1.01g/mol H). If you had two moles of C2H6, you would multiply 2 mol C2H6 (2(12.01g/mol C)+6(1.01g/mol H))

Answer 4

In order to convert an element's mass to moles, you must use the molar mass (either 1 mole/ ___g or ___g/ 1 mole).

For example, when converting 300g or Hydrogen gas to moles, you must multiply that initial amount by the molar mass of H2. So 300g H2 (1mol/ 2gH2) = 150 mol H2.

Answer 5

# of moles = Mass÷ Formula weight

Example:

6 grams of Carbon atoms

Carbon has an atomic mass of 12 grams so according to the Equation

# of moles = 6÷ 12 = 0.5 moles

For a compound such as CO2 , Formula weight = ( 1 mole of carbon atom weighs 12 grams + 2 moles of oxygen atoms weighs 32 grams ) 44 grams.

Example: 24 grams of carbon dioxide = 24÷ 44 = 0.5454moles

Answer 6

Divide mass by number of moles to find the value of molar mass.

You just have to know the formula:

n (mol) = m (mass in gram) / M (molar mass in gram per mole)

So m = n x M

or M = m / n

Answer 7

by multiplying molar mass of that thing with the number of moles

EG:- what is the mass of 2 moles of calsium sulphate?

2mol *136.14gmol-1 =272.28 g

which means if one mole weight 136.14g(x) then 2 moles weight x*2

Answer 8

to convert mass into moles you divide by the molar mass. You cannot convert molar mass directly to moles.

Answer 9

To convert mass to moles, you use the equation n= m/M

n is moles, m is mass, M= Molar mass, which is the mass of the atoms in the formula or substance.

Answer 10

The mole is the molar mass of a compound in grams.
