Answer:
The lowest whole number mass ratio of nitrogen that combines with a given mass of oxygen is 1:1
Explanation:
In compound A, we have 14 g of nitrogen combine with 16 g of oxygen
In compound B, we have 14 g of nitrogen combine with 32 g of oxygen
Therefore, we have
A B
Ratio of molar masses 14:16 14:32
Mass of O that combine with 1 g of N 1.14 2.29
Dividing by the smallest mass ratio 1 2
Therefore the lowest whole number mass ratio at which oxygen and nitrogen can combine = 1:1.
