What is the percent CdSO₄ by mass in a 1.0 molal aqueous CdSO₄solution? A)1.00 * 10^-3 % B)0.100 % C)17.2 % D)20.8 % E)24.4 %

Question

Quizplus · Accepted Answer

A 1.0 molal solution means 1 mole of CdSO4 is dissolved in 1 kg of water. The molar mass of CdSO4 is approximately 208 g/mol. Therefore, the mass of the solution is 1000 g (water) + 208 g (CdSO4) = 1208 g. The percent by mass is (208 g / 1208 g) * 100% = 17.2%.
