Answer:

Molar mass of substance = 40.0 g/mol

Step-by-step explanation:

• 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
