Ethylene glycol, antifreeze, has a density of 1.11 g/cm^3.a. What is the mass, in grams, of 410 mL of ethylene glycol?
Automobile antifreeze is made by mixing equal volumes of ethylene glycol (d=1.114 g/mL, MW= 62.07 g/mol) and water (d=1.00 g/L, MW= 18.02 g/mol). Assume that the volume are additivr, calculate concentrationin the following units:
