    Question: How many quanta are there in 1 µEinstein?

    Options:

    5.074 x 10²³
    6.02 x 10¹⁷
    6.02 x 10⁻²³
    6.02 x 10²³

    ✅ Explanation:
    -An Einstein is a unit of energy used in photochemistry, representing one mole of photons.
    -1 µEinstein (microEinstein) is equal to 10⁻⁶ Einsteins.
    -Avogadro's number (6.02 x 10²³) represents the number of entities (atoms, molecules, ions, etc.) in one mole.
    -Therefore, 1 µEinstein contains (10⁻⁶ moles of photons) * (6.02 x 10²³ photons/mole) = 6.02 x 10¹⁷ photons.
