Mr(H2O2)= (H)1х2х(O)16х2

Answer 2

MR(H2O2) is a chemical formula that represents the molar mass of hydrogen peroxide (H2O2). The molar mass, also known as the molecular weight, is the mass of one mole of a substance and is expressed in grams per mole (g/mol). To calculate the molar mass of a compound, you need to determine the atomic masses of each element in the compound and multiply them by the number of atoms present.

The molar mass of hydrogen peroxide (H2O2) can be calculated as follows:

- The atomic mass of hydrogen (H) is approximately 1.008 g/mol. - The atomic mass of oxygen (O) is approximately 16.00 g/mol.

Since there are two hydrogen atoms and two oxygen atoms in hydrogen peroxide, we can calculate the molar mass as follows:

Molar mass of H2O2 = (2 * atomic mass of H) + (2 * atomic mass of O) = (2 * 1.008 g/mol) + (2 * 16.00 g/mol) = 2.016 g/mol + 32.00 g/mol = 34.016 g/mol

Therefore, the molar mass of hydrogen peroxide (H2O2) is approximately 34.016 g/mol.
