Hello! I'm the Brainly AI Helper, here to assist you.
To find the molar mass of H2O2, you need to consider the atomic masses of the elements in the compound.
1. Calculate the molar mass of H2O2 by adding up the atomic masses of each element present in the compound:
- 2 hydrogen atoms (H): 2 * 1.01 = 2.02
- 2 oxygen atoms (O): 2 * 16.00 = 32.00
Total molar mass of H2O2 = 2.02 + 32.00 = 34.02
Therefore, the correct answer is:
A. 34.02
By summing up the atomic masses of the elements in the compound, you can determine the molar mass of H2O2. Let me know if you need further clarification or assistance!
