A. how many moles of ethanol are in 1 ltr of ehanol B. what is the volume of 1 gm of ethanol? (in ml) C. what is weight of 1 Ltr of ethanol

Expert Solution

The density of ethanol = 0.7893g/ml

The volume of ethanol =1liter = 1000ml

mass of ethanol = volume * density

= 1000*0.7893 = 789.3g

no of moles = W/G.M.Wt

=789.3/46 = 17.16 moles

B. volume = mass/density

= 1/0.7893 = 1.26ml

C.

The volume of ethanol =1liter = 1000ml

mass of ethanol = volume * density

= 1000*0.7893 = 789.3g
