Calculate the mass of a 0.253mL sample of a liquid with a density of 1.38 g/mL.

The answer is

Explanation:

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

From the question

volume of liquid = 0.253 mL

density = 1.38 g/mL

Substitute the values into the above formula and solve for the mass

We have

mass = 1.38 × 0.253 = 0.34914

We have the final answer as
