To find:
The number of moles
Solution:
We can find the solution by following the given process-
We know that the number of moles is equal to the weight of the substance divided by its molar mass.
The number of moles= Weight of Mg/ Molar mass of Mg
The weight of one mole of Mg= 24.30u
The number of moles can be calculated as follows-
= 19.82/ 24.30
= 0.81 mol
Therefore, the number of moles in 19.82g of Mg is 0.81 mol.
