Question

Calculate the mass percent of HCL in 3.20M solution. The density of solution is 1.10g/ml

Answer 1

Answer:

10.6%

Explanation:

$molarity = 10 \times density \: of \: solution \times mass\% \div molar \: mass \: of \: solute \\ 3.20 = 10 \times 1.10 \times mass\% \div 36.5 \\ 3.2 \times 36.5 \div 10 \times 1.10 \\ mass\% = 10.6\%$
