Ethylene glycol (antifreeze) has a density of 1.11 g/cm3. What is the mass in grams of 387 mL of ethylene glycol?

Answer :

TSO
cm^3 = mL

1.11 g/cm^3 = 1.11 g/mL

Density (g/mL) multiplied by volume (mL) will give us the mass (g)

1.11 g/mL * 387 mL = 429.57 g

And since we have 3 significant figures, we have 430. g.
