The procedures of an experiment state that 1.3 g of copper (Cu) should be produced. However, the scientist’s experiment produces 0.9 g.

What is the absolute error?

1.3 g - 0.8g =

To find the absolute error in this scenario, you need to subtract the measured value from the expected value.

Absolute error = Expected value - Measured value

In this case, the expected value is 1.3 g and the measured value is 0.9 g.

Absolute error = 1.3 g - 0.9 g = 0.4 g.

Therefore, the absolute error in this experiment is 0.4 grams.
