Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
mol = mass : molar mass
mass = mol x molar mass
Molar mass = 58,6934 g/mol
Input the value :
mass = 0.0321 x 58,6934 g/mol
mass = 1.884 g
