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

Sagot :

Answer:

288g

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
