Question
In $25 \mathrm{~g}$ of a $7.5 \%$ by mass solution of $\mathrm{CaSO}_{4}$(a) how many grams of solute are present?(b) how many grams of solvent are present?
Step 1
5% by mass solution of CaSO4, which means that there are 7.5 grams of CaSO4 in every 100 grams of the solution. We are given 25 grams of the solution, so we need to find out how many grams of CaSO4 are in these 25 grams. To do this, we can set up a Show more…
