Calculate the molarity of water if its density is `1000 kg//m^(3)`.

Text Solution

Verified by Experts

Molarity of water means number of moles of water in 1 litre of water
`"1 L of water = 1000 cm"^(3)"= 1000 g "(because d = 1000"kg/m"^(3)="1 g/cm"^(3))`
`"1000 g "H_(2)O=(1000)/(18)"mles = 55.56 moles"`
Hence, `" molarity = 55.56 M."`
