A food label lists contents per 100 g. What does that let a buyer read directly?

AThe price per packet
BThe percentage by mass
CThe shelf life in days
DThe volume in litres
Answer & Solution
Correct answer: B. The percentage by mass
1. Many nutrition labels give contents per 100 g. 2. Because 100 g is a hundred units, the number can be read as a percentage. 3. It tells nothing directly about price, shelf life or volume. _Source: Wikipedia, Gram, Uses_
