Question

What is the mass(g) of 9.00 moles of water?

Answer 1

Hey There !:

Molar mass of H₂O = 18.01 g/mol

Therefore:

1 mol H₂O ----------------- 18.01 g/mol

9.00 moles ---------------- ( mass of H₂O )

mass of H₂O = 9.00 x 18.01 / 1

mass of H₂O = 162.09 / 1

mass of H₂O = 162.09 grams

I hope that it helps !
