Step 1

In chemistry, there are many ways to check the deviation of experimental data from the accurate value. These different methods provide the difference between accuracy and precisions of the experimental data which can be further used to calculate the error percentage in the experiment.

Step 2

Calculate moles of magnesium:

Molar mass of Mg= 24.3 g/mol

Mass of Mg = 15.0 g

1 mole
0.617 moles
15.0 g
