Question

Quizplus · Accepted Answer

The substance has a total mass of 100.05 g (35.0 g N + 5.05 g H + 60.0 g O). In a 153-g sample, the amount of hydrogen can be found by setting up a proportion based on the original composition. The proportion of hydrogen in the original substance is 5.05/100.05. To find the amount in a 153-g sample, multiply this proportion by 153, resulting in approximately 7.72 g of hydrogen.
