Question
A solution contains 20g of solute in 180g of solvent. If the solvent is water, what is the concentration of the solution in terms of mass by mass percentage
Options
A)
11.%
B)
22.2%
C)
10%
D)
20%
The correct answer is C.
Explanation:
Mass of Solution = Mass of Solute + Mass of Solvent → 20g + 180g
: Mass of Solution = 200g
Mass Percent = \(\frac{\text{Mass of Solute}}{\text{Mass of Solution}} * 100%\)
Mass percent = \(\frac{20}{200} * 100%\)
Mass percent = 10%
