If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.

What is molarity?

Molarity is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of moles of solute per liter of solution.

We want to find the moles of iron (II) nitrite (solute) in 125 mL of a 3.5 M solution. We will use the definition of molarity.

M = n / V(L)

n = M × V(L) = 3.5 mol/L × 0.125 L = 0.438 mol

where,

  • M is the molarity.
  • n is the number of moles.
  • V(L) is the volume of the solution in liters.

If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.
