Question

In an experiment to determine the density of a liquid, an error of no more than 5.0%

permitted. The true value for this density is 1.439 2 g/cm²

Answer 1

Complete question is;

In an experiment to determine the density of a liquid, an error of no more than 5.0% permitted. The true value for this density is 1.4392 g/cm²

What are the maximum and minimum values which a student may obtain to fall within the acceptable range.

Answer:

Maximum = 1.5112

Minimum = 1.3672

Step-by-step explanation:

We are told the true value for the density is 1.4392 g/cm².

We are also told that the error should be no more than 5%(0.05).

This means the acceptable range of values would be;

1.4392 ± 0.05(1.4392)

This gives;

1.4392 + 0.05(1.4392) = 1.5112

Or

1.4392 - 0.05(1.4392) = 1.3672

Thus,

Maximum = 1.5112

Minimum = 1.3672
