Question

· The density of water at room temperature is
0.997 g/cm3. Calculate the molarity of
water​

Answer 1

Answer:

55

Explanation:

Density given = 0.997g/cm3 but it should be 0.997 kg/m3 only then it can be written as 997g/cm3.

Molar mass = 18g/mol

Molarity = no.of moles / 1 litre

assume the volume to be 1cm3

• Molarity = 997/18= 55...
