<u>Answer:</u> The average of the densities of the given measurements is 1.363 g/mL
<u>Explanation:</u>
The equation used to calculate density of a substance is given by:
We are given:
First measured value of density, = 1.019 g/mL
Second measured value of density, = 1.498 g/mL
Third measured value of density, = 1.572 g/mL
Putting values in above equation, we get:
Hence, the average of the densities of the given measurements is 1.363 g/mL
