Question

A sample of hydrogen peroxide (H202) has 2.0 grams of hydrogen (H) and 32 grams of oxygen (O). What is the percent composition of hydrogen peroxide

Answer 1

O = 94.117%

H = 5.882%

Step-by-step explanation:

Hydrogen peroxide (H202) Molar Mass = 34g

OH 1- 17g/mol

H 1+ = 1g/mol

O = 16g/mol

2 Grams H

32 grams O

Percentage composition of Hydrogen peroxide

O = 32/34 = 94.117%

H = 2/34 = 5.882%
