science chemistry# How do you find the molar mass of sodium?

Last Updated: 13th April, 2020

**molar mass**of NaCl canbecalculated for finding the atomic

**mass of sodium**(22.99g/mol) and the atomic

**mass**of chlorine (35.45 g/mol)andcombining them. The

**molar mass**of NaCl is58.44g/mol.

Likewise, what is the molar mass of sodium?

22.989769 u

Also Know, what is the mass of a formula unit of NaCl? One **formula unit of sodium chloride**(**NaCl**)would weigh 58.44 amu (22.98977 amu for Na + 35.453amu for Cl), soa mole of **sodium chloride** would weigh 58.44grams. Onemolecule of water (H_{2}O) would weigh 18.02amu(2×1.00797 amu for H + 15.9994 amu for O), and a moleofwater molecules would weigh 18.02 grams.

Then, what's the molar mass of sodium hydroxide?

39.997 g/mol

How many moles are in a gram?

Amazingly, there are 6.02x10^23 atoms in each ofthesamples above. A sample of 12 **grams** of carbon is equaltoone **mole**. The amount of **moles** in a substance canbedetermined using that substance's molar mass. The molar mass istheamount of **grams** in one **mole** ofasubstance.
