The values obtained in the measurement of the mass of products from the same reaction are precise but not accurate.

Recall that:

• Precision refers to the closeness of repeated measurements made on the same variable
• Accuracy refers to the proximity of a measurement to its true, predetermined value.

In this case, one can see that the repeated measurements of the mass of the products were close to each other with a range of 0.02 g.

The average of the measurement can be calculated such that:

8.83 + 8.84 + 8.82/3 = 8.83 g

The predetermined mass of products from the reaction is 8.60 g. The difference from the average measurement can be calculated as:

8.60 - 8.83 = 0.23

The difference between the measurement and true value is significant. thus, the result is not accurate.
