Question

How many molecules are in 12.5g of water (H2O)? Molar mass Help asap

Answer 1

Answer:

Explanation:

18.01528 g/mol. I googled this, but it would be 16 for O plus 2 for the 2 H's. 18 g/mol divided by 12.5g=1.44 mol of H20.

1.44mol*$6.02*10x^{23}$ molecules/mol= 8.6688*10^23.

Answer 2

The answer is 18.015 i think
