Mass of a liquid

Question

a student pours 22.5 ml of a liquid that has a know density of .1478 g/cm3 what is the mass of the liquid

Answer 1

ml means milliliter

 

cm³ means cubic centimeter, sometimes shown as cc

 

In fact, these are the same -- 1 ml = 1 cm³

 

That means that 22.5 ml is the same as 22.5 cm³.  So to find the mass, you just have to multiply the volume by the density without changing any units.  That results in 22.5 x .1478 = 3.3255 grams.
