Answer:

Q = 28538.1 J

Explanation:

As we know that heat require to vaporize the ethyl alcohol is given as

Q = mL

here we know that

m = mass = 33.3 gram

L = latent heat of fusion = 857 J/g

now from above formula

Q = (33.3 gram) \times (857 J/gram)

Q = 28538.1 J

so heat required in three significant figures is given as

Q = 2.85\times 10^4 J

so heat required to vaporize ethyl alcohol is 2.85\times 10^4 J
