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: 15.0%

Step-by-step explanation:

Answer 2

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

Step-by-step 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}}* 100`

Where,

Mass of hydrogen = 41.4 grams

Mass of compound = 276 grams

Putting values in above equation, we get:

`\%\text{ composition of hydrogen}=(41.4g)/(276){* 100`

Percentage composition of hydrogen in a given compound = 15%
