Group of answer choices

molar mass and Avogadro's constant

molar mass only

Avogadro's constant only

formula mass, molar mass, and Avogadro's constant

Answer 1

Molar Mass and Avogadro's constant

Explanation:

• Molar mass is calculated by using the mass chemical compound, and the amount of substance. So, to find the molar mass of a particular element or the compound, we have to divide the mass of the given chemical compound or the chemical element( grams) by amount of substance ( moles).

• We can add the standard atomic mass (g/mole) of constituent atoms to find the molar mass of the compound.

• To convert atoms to molecules, we have to dive the number of atoms by Avogadro constant which is 6.022 x 10^23.
