We are a given a mass of milk chocolate of about 12.630 g which contains 8.315 g of sugar. We are tasked to solved for the mass percent of sugarin the milk chocolate. To solve for this, simply follow the formula

% sugar = (mass of sugar / mass of milk chocolate) * 100%

% sugar = (8.315/12.630) * 100%

%sugar = 65.84 %

Therefore, the milk chocolate contains 65.84% of sugar.

America Wiley · Answer 2

For this case you can calculate the sugar percentage present by a simple rule of three:

12,630 g - - - > 100%

8.315 g - - - > x

Clearing x

x = (8.315 / 12.630) * (100) = 65.84%

Therefore, there is 65.84% sugar in 12,630 g milk chocolate bar
