A compound is broken down into 34.5 g of element A, 18.2 g of element B, and 2.6 of element C. What is the percent (by mass) of each element?

Respuesta :

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!
