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?
Answer







8.73% LiOH








14.6% LiOH








6.85% LiOH








12.7% LiOH

Answer 1

if you know grams of solute and grams of total solution, what's the percentage?

Answer 2

Don't know :O

Answer 3

33.7g of LiOH get dissolved in water. That's the mass of solute. The solution has a final mass of 231g. That's the mass of the solution. Divide.

Answer 4

14.6?

Answer 5

The answer is 14.6%. It's a simple division: 33.7 divided by 231, times 100 to get the percent.
