How many moles does Cl2 have?
Cl2 is made up of 2 chlorine atoms. Each chlorine atom has a molar mass of 35.5 g/mol (from the periodic table). Thus, the molecule Cl2 has a molar mass of 71.0 g/mol.
How do I find moles from grams?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
How do you calculate the moles of an element in a compound?
Once you've found the molecular weight, you know the weight of one mole of a compound. To find the number of moles in a sample, simply weigh it and divide the weight by the molecular weight. The quotient is equal to the number of moles.

How do you calculate the number of moles?
To find the number of moles in a sample, simply weigh it and divide the weight by the molecular weight. The quotient is equal to the number of moles. Example: How many moles are there in 300 grams of sodium bicarbonate? The molecular weight of sodium bicarbonate is 84 grams/mole.
How mole is calculated?
If you want to know how many moles of a material you have, divide the mass of the material by its molar mass. The molar mass of a substance is the mass in grams of one mole of that substance. This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units (amu).
How many atoms of phosphorus are present in 0.25 mole of P4?
Or simply 1 mole of P4 molecule contains 4 moles of P atom, therefore 0.25 mole of P4 molecule contains 1 mole of P atom. Therefore, 0.25 mole of P4 contains 6.023*10^23 atoms.
How many moles of phosphorus are in 25 g phosphorus?
1 Answer. 0.352 moles of phosphorus atoms are present in this quantity.
How do you calculate moles produced?
Determine the moles of product produced by dividing the grams of product by the grams per mole of product. You now have calculated the number of moles of every compound used in this reaction. 41.304 g of NaCl ÷ 58.243 g/mol = 0.70917 moles of NaCl.
