Question

Calculate mass of 0.5 mole of water​

Answer 1

Explanation:

18g of H2O=1 mole

? g of H2O=0.5 mole

Mass of 0.5 mole of water=(0.5*18)/1=9g

Answer 2

Answer:

Explanation:

The answer is

The mass of 1 mole of water molecules = 18 g

So,

the mass of 0.5 mole of water molecules is

             

              = 18 x 0.5

               =9.0 g
