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

Answer»

SOLUTION :Molarity of water MENAS NUMBER of moles of water in 1 litre of water
` "L of water"= 100 cm^(3)= 1000 G""(because d=1000kg//m^(2)=1g//cm^(3))` LTBRGT `1000gH_(2)O=(1000)/(18)"moles"="55.56 moles."`
`therefore"Molarity of water"=55.56"mol L"^(-1)`.
