Final answer:
To find the molarity of a 33.7 molal HNO3 solution with a density of 1.35 g/mL, the molality, density, and molar mass of HNO3 are used in a calculation involving unit conversions.
Step-by-step explanation:
The question pertains to determining the molarity of a commercial nitric acid solution with a given molality and density. Molarity is defined as the number of moles of solute per liter of solution. To calculate molarity, we can use the formula:
Molarity (M) = Molality (m) * Density (d) / Molar Mass of HNO3
Given that the molality of the HNO3 solution is 33.7 m and the density is 1.35 g/mL, we first have to convert the density to g/L, and then calculate the moles of HNO3 based on its molar mass, which is approximately 63 g/mol.
After performing the required calculations, which involve converting volume to liters and taking into account the molar mass, one would obtain the molarity of the solution.
