Ammonia is composed of hydrogen and nitrogen in a ratio of 9.33 g of nitrogen and 2.00 g of hydrogen. if a sample of ammonia contains 6.28 g of hydrogen, how many grams of nitrogen does it contain?
9.33N/2H=6.28N/??
solve for ??
To find out how many grams of nitrogen are in the sample of ammonia, we can use the given ratio and the amount of hydrogen in the sample.
The ratio states that for every 9.33 g of nitrogen, there are 2.00 g of hydrogen. We can set up a proportion based on this ratio:
9.33 g N / 2.00 g H = x g N / 6.28 g H
Cross-multiplying, we get:
(9.33 g N)(6.28 g H) = (2.00 g H)(x g N)
58.456 g NH = 2x g N
Now we can solve for x:
x = (58.456 g NH) / 2
x = 29.228 g N
Therefore, the sample of ammonia contains 29.228 grams of nitrogen.
