A sample with molar mass of 34.00g/mol is found to consist of 5.9783% H and 94.0217% O. Find it’s molecular formula

The formula is H202 (hydrogen peroxide, known as hydrogen peroxide)

Explanation:

100%34g

5, 9783%---X= (5, 9783%x 34g)/100% =2 g

1g---1 atom of H

2gx= 2g x 1 atom of H/1g = 2 atom of H

100%34g

94, 0217%---X= (94,0217%x 34g)/100% =32 g

16g---1 atom of 0

32gx= 32g x 1 atom of 0/16g = 2 atom of 0
