MASS/Volume

A chemist needs a 25.5-kg sample of ethanol for a large-scale reaction. What volume in liters of ethanol should the chemist use? The density of ethanol is 0.79g/cm^3

Given: 23.5 kg ethanol


Density = 0.79 g/ cm^3




Find: Volume




Solution map: kg > g > cm^3 > mL > L


23.5kg x 1000g/ 1kg X 1 cm^3/0,789 g


x1ml/1 cm^3 X 1L/100mL = 29.7845 L = 29.8 L
