If a bottle of olive oil contains 1.4 kg of olive oil, what is the volume, in milliliters ( mL ), of the olive oil?
Serhud [2]

We know that density of olive oil = 0.93 g/mL

Given that mass of olive oil = 1.4 kg or 1400 g because 1000 g = 1.0 kg

From the definition of density;

Volume = mass/ density

= 1400 g/ 0.93 g/mL

=1505 mL
