An engineer has the task of producing an aluminum alloy with a density of 3.0 grams per cubic centimeter. she comes up with the perfect alloy and saves a sample of it. which mass and volume measurements correspond to this sample? 7 g and 2.3 cm³ 10 g and 7 cm³ 15 g and 5 cm³ 21 g and 8 cm³

The correct answer is 15 g and

Explanation:

Density of an object is defined as the ratio of object's mass and volume.

Mathematically,

We need to find the mass and volume measurements which give us the density of . For that we find out the density in all the options and match the required density.

From the given options:

1. 7 g and

Mass = 7 g

Volume =

Putting values in density equation, we get:

2. 10 g and

Mass = 10 g

Volume =

Putting values in density equation, we get:

3. 15 g and

Mass = 15 g

Volume =

Putting values in density equation, we get:

4. 21 g and

Mass = 21 g

Volume =

Putting values in density equation, we get:

Hence, the measurements 15g and give us the density as
