Which formula can be used to calculate the molar mass of hydrogen peroxide (H2O2)? (5 points) Select one:
a. molar mass of H + molar mass of O
b.2 x molar mass of H + molar mass of O
c. molar mass of H + 2 x molar mass of O Incorrect
d.2 x molar mass of H + 2 x molar mass of O

option d (2×molar mass of H +2×molar mass of O

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
