Answer:
Explanation:
Given
mass of ethanol 
mass of aluminium cup 
both are at an initial temperature of 
specific heat of ethanol 
specific heat of aluminium 
specific heat of ice 
specific heat of water 
Latent heat of fusion 
suppose m is the mass of ice added
Heat loss by Al cup and ethanol after
is reached

Heat gained by ice such that ice is melted and reached a temperature of 

Comparing 1 and 2 we get

Thus 23.65 gm of ice is added
Beta particles ARE electrons.
Also, in one of the great coincidences of Physics, electrons ARE beta particles.
