1. Compound A contains 14 g of nitrogen for each 16 g of oxygen. Compound B contains 14 g of nitrogen for each 32 g of oxygen. What is the lowest whole-number mass ratio of nitrogen that combines with a given mass of oxygen

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.
