Question

If 33.7 grams of LiOH dissolve in enough water to make a 231-gram solution, what is the concentration in percent by mass?

14.6% LiOH

12.7% LiOH

8.73% LiOH

6.85% LiOH

can anyone explain how to solve this?

Answer 1

\(\huge\text{Concentration in % mass=}\)\(\huge\frac{mass~of~solute}{mass~of~solvent}*100\)

Answer 2

= \(\huge\frac{33.7}{231}*100\) = 14.588 \(\approx\) 14.6%
