The density of mercury metal is 13.6 g/mL. What is the mass of 3.55 mL of the metal?
To calculate the mass of the object, we have to use the following formula:
- Density will have units of
The mass has units of grams,
The volume will have units of
We are given the density and volume, both of which have good units so all we have to do is rearrange the equation to solve for the mass:
Thus, the object has a mass of 48.3g.
