Question

What is the percent composition of hydrogen if a sample is found to contain 7 grams of hydrogen, 32 grams of nitrogen, and 7 grams of carbon?

Answer 1

Answer: The percent composition of hydrogen in the sample is 15.22 %

Step-by-step explanation:

We are given:

Mass of hydrogen = 7 grams

Mass of nitrogen = 32 grams

Mass of carbon = 7 grams

Total mass of the sample = 7 + 32 + 7 = 46 grams

To calculate the percentage composition of hydrogen in sample, we use the equation:

`\%\text{ composition of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of sample}}* 100`

Mass of sample = 46 g

Mass of hydrogen = 7 g

Putting values in above equation, we get:

`\%\text{ composition of hydrogen}=(7g)/(46g)* 100=15.22\%`

Hence, the percent composition of hydrogen in the sample is 15.22 %
