The mass concentration of the 0.75 mol.dm-³ AgNO3 solution is 127.5 g/dm³.

What is concentration?

Concentration is the amount of a solute present ina a given volume of solution.

Concentration of solutions can either be expressed as:

  • molar concentration
  • Mass concentration
  • Percentage concentration

The concentration of 0.75 mol.dm-³ AgNO3 is a molar concentration.

The concentration can be converted to mass. concentration as follows:

  • Mass concentration = molar concentration × molar mass

molar mass of AgNO3 = 170 g/mol

Mass concentration = 0.75 × 170 = 127.5 g/dm³.

Therefore, the mass concentration of the AgNO3 solution is 127.5 g/dm³.
