Question

The density of water at 0.997770 g/mL. What is the true mass of 25.00 mL of water at 22 degrees celsius?

Answer 1

We will multiply the density of water at by the volume of water, 25.00 mL.

0.997770 g/mL(25 mL) = 24.94425 g.

Note: I am ignoring the number of significant figures in this problem to answer the actual "true mass" of water. However, in all academia, these should not be ignored.
