What is the mass of an object with a density of 15 g/ml and a volume of 3 ml ?

12 g

18 g

45 g

5 g

Text Solution

Verified by Experts

The correct Answer is:

We are given the density and volume, thus, we have to rearrange the equation to solve for the mass Density`xx`Volume=Mass/Volume`xx` Volume Density`xx` Volume=Mass
15 g/mL`xx` 3mL=Mass
Thus, the object has a mass of 45 g.
