Question

a student obtained the following data when dinitrogen and dioxygen react together to form different compound Mass of dinitrogen Mass of dioxygen 14g 16g 14g 32g 28g 32g 28g 80g what is the ratio between the different masses of dioxygen which combine with 14g of dinitrogen?

Open in App

Solution

The masses of dioxygen that combine with 14g of dinitrogen are:

16g, 32g. 14g, 40g.

They are in the ratio 1:2:1:2.5 or whole number ratio 2:4:2:5.
