Question

molarity of water when density of water is 1000kg./m^3

Answer 1

1 liter water =1 kg

or 1000 ml water =1 kg [Given d=1000kg/m3]

Moles of water present in 1000ml=100018=55.55

Hence molarity of water =55.55M

Hence a is the correct answer.

ye 1000 upon 18 kaise aya plzz tell me in detail

Mass=density×volume=1×1000 and dividing by 18(molecular mass) gives moles
