Gelatin has a density of 1.27 g/cm³. if you have a blob of gelatin dessert that fills a 2.0 liter bottle, what is its mass?

density = mass / volume so mass = density x volume

2 litres = 2000cm^3


mass = 1.27 x 2000 = 2540g = 2.54 kg

There are 1,000 cm³ in 1 liter, 2,000 cm³ in 2 liters.

Each cm³ of gelatin has  1.27 grams of mass in it.

There are 2,000 cm³ in the whole blob, so the total mass is

            (2,000 cm³) · (1.27 g/cm³)  =  2,540 grams

                                                         or    2.540 kilograms  .
