Answer:

The answer is 1.35 moles

Explanation:

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

[tex]n = \frac{M}{m} \\ [/tex]

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

[tex]n = \frac{24.3}{18.02} \\ = 1.348501664...[/tex]

We have the final answer as

1.35 moles

Hope this helps you
