Answer:
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
2g----x= 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
32g----x= 32g x 1 atom of 0/16g = 2 atom of 0
