What is the volume of an object that has a mass of 3.5 grams and has a density of 2.50 g/mL? Include units and proper sig figs l
jolli1 [7]

1.4mL

Explanation:

Given parameters:

Mass of object = 3.5g

density = 2.5g/mL

Unknown:

Volume of the object = ?

Solution:

Density is the mass per unit volume of a body. It is an intensive property that is the same for the same substances.

   Density = \frac{mass}{volume}

  since the volume is unknown; we make it the subject of the formula;

 Volume = \frac{mass}{density}

Volume = \frac{3.5}{2.5}

Volume of the object = 1.4mL
