Question

If 35.8 grams of LiCl are dissolved in 184 grams of water, what is the concentration of the solution in percent by mass? (3 points)

Answer 1

The answer to this question is 16.3%

Answer 2

Answer : The concentration of solution in percent by mass is 16.3 %

Explanation :

Percent by mass : It means that the mass of solute present in the mixture and multiply by 100.

Given:

Mass of LiCl = 35.8 g

Mass of water = 184 g

First we have to calculate the mass of mixture.

Mass of mixture = Mass of LiCl + Mass of water

Mass of mixture = 35.8 g + 184 g

Mass of mixture = 219.8 g

Now we have to calculate the concentration of solution in percent by mass.

`\text{Concentration of solution in percent by mass}=\frac{\text{Mass of }LiCl}{\text{Mass of mixture}}* 100`

`\text{Concentration of solution in percent by mass}=(35.8g)/(219.8g)* 100=16.3\%`

Therefore, the concentration of solution in percent by mass is 16.3 %
