Answer: 18.75%
Step-by-step explanation:
The percent strength of a solution is given by :-
[tex]\% \text{ Strength}=\dfrac{\text{Mass of solute in g}}{\text{Volume of solution in mL}}\times100[/tex]
Given : A solution of ibuprofen contains 150g in 800mL .
Then, the percent strength of this solution will be :-
[tex]\% \text{ Strength}=\dfrac{150}{800}\times100\\\\\Rightarrow\ \% \text{ Strength}=18.75\%[/tex]
Hence, the percent strength of this solution = 18.75%
