Answer to Question #18118 in Chemistry for Sadaam Ahmed
Question #18118
The percentage composition of a compound is 79.9% copper and 20.1% sulphur. The mass of a sample of the compound is 160.0 g. What are the masses of the copper and sulphur in the sample?
Expert's answer
m = mcompound * W
m(Cu) = 160 g * 0.799 = 127.84 g
M(S) = 160 g * 0.201 = 32.16 g.
m(Cu) = 160 g * 0.799 = 127.84 g
M(S) = 160 g * 0.201 = 32.16 g.
