Question

What mass (in gram) of water would you need to have 16.0 moles of H20?

Answer 1

288g

Step-by-step explanation:

Given parameters:

Number of moles of H₂O = 16moles

Unknown:

Mass of the water = ?

Solution:

To solve this problem, first find the molar mass of H₂O;

Molar mass of H₂O = 2(1) + 16 = 18g/mol

Mass of H₂O = number of moles x molar mass

= 16 x 18

= 288g
