Question

A sample of ammonia contains 9 grams of hydrogen and 42 grams of nitrogen.Another sample contains 5 grams of hydrogen.Calculate the amount of nitrogen in the second sample

Answer 1

Best Answer

In the first sample we see that the amount of nitrogen is 42/9 = 4.667 times more massive than the amount of hydrogen. If the second sample is also ammonia, it should also contain 4.667 tomes more nitrogen by mass. 6-g x 4.667 = 28-g of nitrogen.
