Answer: The mass percent of hydrogen in hydrogen peroxide is 5.88 %.
Explanation:
In [tex]H_2O_2[/tex], there are 2 hydrogen atoms and 2 oxygen atoms.
To calculate the mass percent of element in a given compound, we use the formula:
[tex]\text{Mass percent of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Molar mass of hydrogen peroxide}}\times 100[/tex]
Mass of hydrogen = [tex](1\times 2)=2g[/tex]
Mass of hydrogen peroxide = 34 g
Putting values in above equation, we get:
[tex]\text{Mass percent of hydrogen}=\frac{2}{34}\times 100=5.88\%[/tex]
Hence, the mass percent of hydrogen in hydrogen peroxide is 5.88 %.
