A cylindrical barrel filled entirely with a certain volatile

Question

A cylindrical barrel filled entirely with a certain volatile chemical has to be shipped to a disposal facility. If the chemical weighs .9 kg/l, what is the total mass of the chemical in the barrel?

(1) The height of the barrel is four times the diameter

(2) The circumference of the barrel is 4pi meters

Fig · Answer

for me (C)

We need information about the volume. Stat 1: The volume could be any value. INSUFF Stat 2: As the radius is in the calculus of cylendar volume with a non linear relation (r^2), we need to have a relation between the height and the radius. INSUFF Both statments give the necessary information to conclude.

I think the answer is E.
With both the hints together, we get the volume in meter ^ 3. But the given mass is in /liter.
So - insufficient.

1 l = 1 dm^3 = 10^-3 m^3

I think that ratio is true only for water on a specific temperature, certainly not for all liquids. The question says volatile liquid. We do not know the conversion ratio for that liquid. 

I thought it is a trap... not sure whether GMAT will try to test these things

By the way, what is the OA?

Rayn · Answer

I think you might be reasoning too far into the question anindyat.

I did not know the conversion for a litre to cubic meters. But now I do, it certainly must be C.

OA please?

tennis1ball · Answer

C. both can determine the volume.

GMATT73 · Answer

I also selected (C) but the OA given is (E) for this exact reason. The source is the McGraw Hill's GMAT CAT#2. 

Very tricky question. Could be an experimental clone crafted by the publishers of the book/software???

Strange question

... We will transport the liquid in opened tanks in order to not only evaporate, but also deverse some liquid during the trip

And finally, any liquids are volatile (even solids are

) :p

yezz · Answer

As a matter of phisics .....and as Fig mentioned , i know since school time that all liquids are volatile , like all metals are rustable only differs in the rate of this happening........ Man this is a funny question , oceans apart from Gmat that challenge you in the basic knowledge that everyone knows.........

:wink:
