Answer #1

density of ethanol = 0.79kg/lit=790gms/lit=790gms/1000ml=0.79gms/1ml

every 100ml of wild turkey consits of 43ml of ethanol.

so 1000ml consists of 430ml of ethanol

hence

mass of ethanol in wild turkey per litre = volumeX density=430 X 0.79 = 339.7gms

so molarity of ethanol in wild turkey is given by
