What is the mass of an object that has the density of 14 g/ml and volume of 10 mL?
To calculate the density of the object, we have to use the following formula:
Density will have units of
#g/(mL)#when dealing with a liquid or units of #g/(cm^3)#when dealing with a solid.
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 140g.
