To acquire the same antifreeze protection necessitates the 76g of propylene glycol to replace each 62g of ethylene glycol. Determine the mass of propylene glycol which is necessary to required replacing the 3.0 gallons of ethylene glycol. When the density of ethylene glycol is given 1.12 g/mL.
Analyze the volume of propylene glycol, in gallons, required to produce the same antifreeze protection as 3.00 gallons of ethylene glycol.
