Question

10g of sugar is dissolved by water to make 200g of solution of sugar. What is the percent by mass of the solution?

a) 2%
b) 4%
c) 5%
d) 8%

Answer 1

The percent by mass of sugar in the solution is calculated to be 5%, which is option c).

Step-by-step explanation:

To calculate the percent by mass of a solution, the mass of the solute is divided by the total mass of the solution, then multiplied by 100%. In the question asked, 10 g of sugar (solute) is dissolved in water to make a 200 g solution. The percent by mass is calculated as follows:

Percent by mass = (mass of solute / mass of solution) x 100%

= (10 g / 200 g) x 100%

= 0.05 x 100%

= 5%

Therefore, the correct answer is c) 5%.
