Question

12.5 g of magnesium gives 20.20 g of magnesium oxide on
burning. The actual mass of magnesium oxide that should
be produced is 20.15 g. Calculate absolute error.
Distinguish between accuracy and precision(any two
points)​

Absolute error: 0.05g

relative error : 0.25%

Accuracy would be referred to as the level of correctness of measurement when compared to its true value.

Precision, on the other hand, refers to the level of absolute exact the measurement is to the strictest manner.
