Calculate molarity of water if its density is 1.00g mL–1 .

Answer»

Volume of solution = \(\frac{mass}{density}\)

Molar mass of H₂O = 1(2) + 16 = 18

Molarity = \(\frac{No.\,of\,moles\,of\,solute}{Volume\,of\,solution}\)

= \(\frac{Density}{Molar\,mass\,of\,H_2O}\)

= \(\frac{1000}{18}\) = 55.56 M
