How many moles are in 13g NaCl?

Question

How many moles are in 13g NaCl?

Answer 1

Atomic mass Na = 23 g (rounded)

Atomic mass Cl = 35.5 g (rounded)

Molecular mass NaCl ≈ 58.5 g

13g  = 13/58.5 = 0.221 moles

Answer 2

there are 58.442 g of NaCl per mole of NaCl

Calculations:

13 g * 1 mole of NaCl / 58.442 g = 0.222442764 moles

Answer 3

take th emolar mass (atomic mass of na + atomic mass of Cl) and divide your 13 by the molar mass

the formula is n=m/M

where

n=mol

m=mass

M=molar mass
