The mass percent of nitric acid HNO 3 in water is 30% with density 1.18 g/cm 3 . The molarity of HNO 3 in the solution needs to be calculated. Concept introduction: Mass percent of any species in the solution can be calculated from its mass and mass of the solution. For example, if mass of the species is x and that of solution is y, the mass percent of the solution can be calculated as follows: % m = x g y g × 100 % The molarity of solution is defined as number of moles of solute in 1 L of the solution. M = n V ( L ) The density of the solution is related to mass and volume of solution as follows: d = m solution V solution The number of moles of substance can be calculated from mass and molar mass as follows: n = m M Here, m is mass and M is molar mass.

Concept introduction:
Mass percent of any species in the solution can be calculated from its mass and mass of the solution. For example, if mass of the species is x and that of solution is y, the mass percent of the solution can be calculated as follows:
%m=x gy g×100%
The molarity of solution is defined as number of moles of solute in 1 L of the solution.
M=nV(L)
The density of the solution is related to mass and volume of solution as follows:
