If the weight of metal oxide is x gram

Asked by admin @ 20/08/2021 in Chemistry viewed by 278 People

what will be the equivalent weight of metal if the weight of metal oxide is x gram containing y gram of oxygen??

Answered by admin @ 20/08/2021

Metal oxide = x gm

Oxygen = y gm

Metal = (x-y) gm

8 gm of oxygen will combine with 8(x-y)/y gm of metal

Equivalent mass of metal = 8(x-y)/y gm
