Well, first we work out the volume of the ethanol.........and get an approximate volume of $2*"quart"$

$"Density, "rho="Mass"/"Volume"$ .

And thus $"Volume"$ $=$ $"Mass"/rho=(1.50xx10^3*cancelg)/(0.79*cancelg*mL^-1)$

$=1898.7*mL=1.899*L$ (this is consistent dimensionally, because the grams cancel out and we are left with units of $1/(1/(mL))=mL$ as required.)

Now $"1 US quart"=0.946*L$ ,

so $(1.899*L)/(0.946*L*"quart"^-1)~="2 quart"$
