If the temperature of 68.8 g of ethanol increases from 40.0(C to 71.3(C, how much heat has been absorbed by the ethanol? (Specific heat of ethanol is 2.44 j/g((C)

Q = 5254.39 J

Explanation:

Given that,

Mass of ethanol, m = 68.8 g

The temperature increases from 40.0°C to 71.3°C.

The specific heat of ethanol is 2.44 j/g°C

We need to find the heat absorbed by the ethanol. We know that the heat absorbed due to the change in temperature is given by :

Put all the values,

So, 5254.39 J of heat is absorbed by Ethanol.
