Understanding the Relationship

* Density is a measure of how much mass is packed into a given volume. It's calculated as:

Density = Mass / Volume

Solving for Mass

1. Rearrange the formula to solve for mass:

Mass = Density x Volume

2. Plug in the given values:

Mass = 0.60 g/mL x 30.0 mL

3. Calculate the mass:

Mass = 18.0 g

Answer: The mass of 30.0 mL of the liquid is 18.0 grams.
