14.0 grams of potassium hydroxide was dissolved to form 100 centimetre cubeof an aqueous solution. What was the concentration of this solution in mol/decimetre cube.

Answer 1

M = mols/dm^3 = mols/0.1
mols = grams/molar mass = 14.0/approx 56 = ?
Substitute into M = mols/L and solve for M.

Answer 2

1.4

Answer 3

Correct! The concentration of the solution is 1.4 mol/dm^3.
