2 Mg(OH)2 have 10 atoms.
1 mole MgO = 40.3044g MgO
1g MgO x 1mol MgO/40.3044g MgO = 0.03 mole MgO

0.010 moles The molar mass of H2SO4 is 98.1 grams per mole. To find out how many moles are present in a given mass, divide the mass by the molar mass. So: 1g/98.1g mol-1 is 0.010 mol.
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
1g = 100cg 6g x (100cg/1g) = 600cg
1g = 100cg 6g x (100cg/1g) = 600cg

About 1 mole
The answer is 0,166.10e23 molecules.
Suppose you have 1g of H2O and you want to convert that to moles. You multiply 1g by the inverse of molar mass to get the moles of H2O: 1g H2O *(1mol H2O/18g H2O)= 0.56 moles of H2O in 1g of H2O. You get 18g = 2(1.008)+1(16.00).
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
Assuming a density of 1g/ml for water, 250.0 mls = 250 g250 g x 1 mol/18 g = 13.9 molesThe answer previously given (247 moles) is incorrect.
First, determine molar mass of CH4: C:12g/mol + 4x H:1g/mol= 16g/mol Then divide by the number of grams. 64g/(16g/mol)= 4 moles of CH4
it is equal because 1g
Let's calculate this:Water density is: 1g/ml1ml * 1g/ml = 1g of water in 1 ml.Next,Water molecular weight, about: 18g/mol1g * 1mol/18g = 1/18 moles = about 0.056 moles in 1ml (=1g) of water.This can be done in one step as:1ml * 1g/1ml *1mol/18g = 1/18 moles of waterCheers,Me
The atomic mass of the compound C6H8O7 is 6(12.0) + 8(1.0) + 7(16.0) = 192.01000mg is equivalent to 1g. Amount of C6H8O7 = mass of pure sample/molar mass = 1/192.0 = 0.00521mol There are 0.00521 moles of C6H8O7 in a 1000mg pure sample.
1g = 1000mg 10mg x 1g/1000mg = 0.01g
