Ethylene glycol (antifreeze) has a density of 1.11 g/cm3.

(a) What is the mass in grams of 387 mL of ethylene glycol?

(b) What is the volume in liters of 3.46 kg of ethylene glycol?

Solution 101P

Here, we are going to find the mass of 387 mL of ethylene glycol. Also, we are going to calculate the volume in litres of 3.46 kg of ethylene glycol.

Step1:

Density of any substance may be defined as mass per unit volume. If ‘d’ be the density, ‘m’ be the mass and ‘v’ be the volume of any substance, then, numerically,

d = ------- (1)

Step2:

(a) Given, volume of ethylene glycol = 387 mL = 387 cm3 [1 mL = 1 cm3]

Density of ethylene glycol = 1.11 g/cm3

Substituting the values in equation (1), we get,

1.11 g/cm3 = m / 387 cm3

m = 1.11 x 387...
