## 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 MgBr_{2} is 1 gram-molecule of MgBr_{2} but 3 gram-atoms of MgBr_{2}.

## 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.
