Calculating the Percent Composition of Hydrogen in Beryllium Hydride
Percent Composition of Hydrogen in Beryllium Hydride (BeH2)
The percent composition of hydrogen is 18.3%.
What is percent composition?
The term percent composition refers to the percentage of a particular component in a compound. It is calculated as the ratio of the mass of that component to the total mass multiplied by 100.
From the law of conservation of mass, the total mass of beryllium hydride (BeH2) is 85.2 g.
Given that the mass of hydrogen is 15.6 g, we can calculate the percent composition of hydrogen as follows:
Percent composition of hydrogen = (15.6 g / 85.2 g) x 100% = 18.3%
What is the percent composition of hydrogen in beryllium hydride (BeH2) if 69.6g of beryllium (Be) react with 15.6 g of hydrogen to produce 85.2 g of BeH2? The percent composition of hydrogen in beryllium hydride (BeH2) is 18.3%.
