The molecular weight of water, H2O is 18.02 g/mol. How many moles of water are in 24.3 g of water?

Explanation:

To find the number of moles given the molecular weight and mass we use the formula

where

n is the number of moles

M is the molar mass

m is the mass of the substance

From the question

m = 24.3 g

M = 18.02 g/mol

We have

We have the final answer as

Hope this helps you
