Is a mole 1 gram?
The term gram-molecule (g mol) was formerly used for “mole of molecules”, and gram-atom (g atom) for “mole of atoms”. For example, 1 mole of MgBr2 is 1 gram-molecule of MgBr2 but 3 gram-atoms of MgBr2.

How do you calculate 1 mole of NaCl?
If you had the compound sodium chloride (NaCl), you would add the mass of 1 mol of sodium and 1 mol of chlorine. This would give you the mass of 1 mol of sodium chloride which would be about 58.443 g.
What is the value of 1 gram mole?
(Often called gram-molecular weight.) A mass of a substance in grams numerically equal to its molecular weight. Example: A gram-mole of salt (NaCl) is 58.44 grams.
How many grams is in 1 mole of chlorine in the table salt?
This means that 1 gram of H is a mole of H; 12 grams of C is a mole of C; 23.0 grams (round 22.99 to 23) of Na is a mole of Na; 35.5 grams of chlorine is 1 mole of Cl; 58.5 grams of chlorine is a mole of NaCl …23.0 grams for Na and 35.5 grams for Cl added together gives 58.5.
How many moles are in salt?
One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.
How do you calculate 1 mole of sodium?
In this example, multiply the grams of Na by the conversion factor 1 mol Na/ 22.98 g Na, with 22.98g being the molar mass of one mole of Na, which then allows cancelation of grams, leaving moles of Na.
How do you find how many grams are in a mole?
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.
