Question

What is the percent composition of hydrogen in a compound if the mass of the initial compound is 276 gram and the mass of collected hydrogen after decomposition is 41.4 grams?

Answer 1

Answer: The percentage composition of hydrogen in the given compound is 15%.

Explanation:

To calculate the percentage composition of hydrogen in a compound, we use the formula:

$\%\text{ composition of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of compound}}\times 100$

Where,

Mass of hydrogen = 41.4 grams

Mass of compound = 276 grams

Putting values in above equation, we get:

$\%\text{ composition of hydrogen}=\frac{41.4g}{276}{\times 100$

Percentage composition of hydrogen in a given compound = 15%
