What is the molar mass of hydrogen peroxide?
To calculate the molar mass of hydrogen peroxide (H2O2), you'll need to know the atomic masses of hydrogen (H) and oxygen (O). Here's how to get the answer:
1. Find the atomic masses of hydrogen (H) and oxygen (O) from the periodic table.
- The atomic mass of hydrogen (H) is approximately 1.008 grams per mole.
- The atomic mass of oxygen (O) is approximately 15.999 grams per mole.
2. Determine the number of atoms of hydrogen and oxygen in one molecule of hydrogen peroxide (H2O2).
- In hydrogen peroxide, there are two atoms of hydrogen (H) and two atoms of oxygen (O).
3. Calculate the molar mass by multiplying the number of atoms with their respective atomic masses and adding them together.
- Molar mass of hydrogen peroxide (H2O2) = (2 * atomic mass of hydrogen) + (2 * atomic mass of oxygen)
= (2 * 1.008 g/mol) + (2 * 15.999 g/mol)
= 2.016 g/mol + 31.998 g/mol
= 34.014 g/mol
Therefore, the molar mass of hydrogen peroxide (H2O2) is approximately 34.014 grams per mole.
The formula for hydrogen peroxide is H2O2, which consists of two hydrogen atoms and two oxygen atoms. To calculate the molar mass, you need to sum up the atomic masses of all the atoms.
The atomic mass of hydrogen is approximately 1.008 grams/mole, and the atomic mass of oxygen is approximately 16.00 grams/mole.
To calculate the molar mass:
2 (hydrogen atoms) * 1.008 grams/mole (atomic mass of hydrogen) + 2 (oxygen atoms) * 16.00 grams/mole (atomic mass of oxygen) = 2.016 grams/mole + 32.00 grams/mole = 34.016 grams/mole
Therefore, the molar mass of hydrogen peroxide (H2O2) is approximately 34.016 grams/mole.
