A compound is broken down into 34.5 g of element a, 18.2 g of element b, and 2.6 g of element

First, find the total mass.

34.5 g + 18.2 g + 2.6 g = 55.3 g

Divide the mass of each element by total mass.

34.5 g / 55.3 g = .62 x 100 = 62% element a

18.2 g / 55.3 = .33 x 100 = 33% element b

2.6 g / 55.3 = .047 x 100 = 4.7% element c

Hope I helped!
