The density of a liquid is 1.25 g/mL. What is the mass of 75.0 mL of the sample?

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

density = 1.25 g/mL

volume = 75.0 mL

We have

mass = 1.25 × 75

We have the final answer as

Hope this helps you

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.
