Question

0.541 mol of C12H22O11 is dissolved in water to make 0.223 L of solution. What is the molarity of this solution

Answer 1

Molarity represents the number of moles of solute per one litre of solution:

M = n/V,

where M - molarity, n - number of moles, V - volume.

As 0.541 mol of C₁₂H₂₂O₁₁ is dissolved in water to make 0.223 L of solution:

M (C₁₂H₂₂O₁₁) = 0.541 mol / 0.223 L = 2.43 mol/L = 2.43 M

Answer: 2.43 M
