a box holds 18 chocolates and has a gross mass of 310 g. each chocolate weighs the same. when 8 chocolates have been eaten, the box and the remaining chocolates together have a mass of 210 g. what is the mass of each chocolate?
The mass of each chocolate candy is 0.1 because you have to find the decimal in both of those numbers so that you would get this answer then subtract to get the amount of mass of a single one.
