Ten grams of sugar are added to a 40-g serving of a breakfast cereal that is 30% sugar. what is the percent concentration of sugar in the resulting mixture?

Mass of the serving = 40 g

Mass % of sugar in the 40 g serving = 30 %

Mass of sugar in the 40 g serving =

10 g of sugar is added.

So the total mass of sugar added = 10 g + 12 g = 22 g

Total mass of the solution = 10 g solute (sugar) + 40 g (serving) = 50 g

Mass % of the resulting mixture =

Mass % of sugar in the

am i too late?
