1)

Mr(CxHy) = D(H2) * Mr(H2) = 58

Mr(Cx) = Mr(CxHy) * w(Cx) = 58 * 0.828 = 48

x = Mr(Cx) / Mr(C) = 4

Mr(Hy) = Mr(CxHy) - Mr(Cx) = 58-48 = 10

y = 10

2)

Mr(Cx) = Mr(CxHy) * w(Cx) = 40 * 0.9 = 36

x = Mr(Cx) / Mr(C) = 3

Mr(Hy) = Mr(CxHy) - Mr(Cx) = 40-36 = 4

y = 4

3)

Mr(Cx) = Mr(CxHy) * w(Cx) = 70 * 0.857 = 60

x = Mr(Cx) / Mr(C) = 5

Mr(Hy) = Mr(CxHy) - Mr(Cx) = 70-60  = 10

y = 10
