A solution is made by dissolving
29 g of sodium lithium chloride
in water to a final volume of
202 mL solution.
What is the weightweight % or percent by mass of the somute
percent by mass of the solute?

99.3%

Explanation:

The percent by mass of the solute can be expressed as:

And for this problem:

So to calculate the percent by mass first we need to calculate the mass of water, to do so we use its density (1 g/L):

Density water = mass water / volume

Now we have all the data required to calculate the % mass:

hope this !
