At 20 Celsius skim milk has a density of 1.033 kilos per liter while light cream has a density of 1.012 kilos per liter. at 20 Celcius, what is the mass of one gallon of skim milk if 1 liter is approximately 0.264 gallons?

Respuesta :

Answer:

Mass of 1 gallon skim milk is 3.92 kg.

Explanation:

Density is the ratio of mass to volume.

Density = (mass)/(volume)

0.264 gallons = 1 L

So, 1 gallon = [tex]\frac{1}{0.264}L[/tex] = 3.79 L

So, mass of 3.79 L of skim milk = (density of skim milk)[tex]\times[/tex](volume of skim milk)

                                                    = [tex](1.033kg/L)\times (3.79L)[/tex]

                                                    = 3.92 kg

So, mass of 1 gallon skim milk is 3.92 kg.
