Raspberry ketone, used to give food a raspberry or blueberry flavor, is composed of 73.14% by mass carbon. How many grams of carbon are in a 260.-g sample of this flavoring?

193 g

Explanation:

The mass percent of a component in a mixture is the mass of the component divided by the total mass of mixture multipled by 100.

% of component A = (mass of component A / mass of mixture) * 100

Substitute and solve for the mass of carbon:

74.13 = (mass of carbon / 260 g of sample) * 100

74.13 * 260. g / 100 = mass of carbon

Mass of carbon = 193g (rounded to 3 significant figures)
