Answer:
Molar mass of substance = 40.0 g/mol
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
