The concentration of the solution produced by the chemist, given that he or she dissolve 0.100 mole of urea in 2.50×10² mL of solution is 0.4 M

How to calculate the concentration of solution?

We know from stoichiometry that concentration of solution is defined as mole of solute in 1 L of solution i.e

Concentration of solution = mole of solute / volume of solution

With the above formula, we can calculate the concentration of the solution the chemist produced. Details below:

  • Mole of solute (urea) = 0.100 mole
  • Volume of solution (urea) = 2.50×10² mL = 2.50×10² / 1000 = 0.25 L
  • Concentration of solution =?

Concentration of solution = mole of solute / volume of solution

= 0.100 / 0.25

= 0.4 M

Therefore, the concentration is 0.4 M

Complete question:

A chemist dissolve 0.100 mole of urea (CH₄N₂O) in 2.50 × 10² mL of solution. What is the concentration of the solution produced by the chemist?
