What is the mass percent of a sugar solution having 15 g sugar dissolved in 63 g of solution?

23.81%

Explanation:

The mass percent of a solution, also known as percentage by weight or w/w%, can be calculated using the formula:

mass percent = (mass of solute / mass of solution) x 100%

In this question;

Mass of solute (sugar) = 15g

Mass of solution (sugar + water) = 63g

Hence,

w/w% = 15/63 × 100

w/w% = 0.2381 × 100

w/w% = 23.81%

Therefore, the mass percent of the sugar solution is 23.81%.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
