<u>Answer:</u>

Molar mass of substance = 40.0 g/mol

<u>Explanation:</u>

• First calculate the number of moles in 3.66 × 10²³ :

no. of moles = number of particles / Avogadro's Number

                     = (3.66 × 10²³)  /  (6.022 × 10²³)

                     = 0.6078 mol

• Now use the following equation to calculate the molar mass:

Molar mass = mass of substance / no. of moles

                   = 24.31 / 0.6078

                   = 40.0 g/mol
