4. A piece of copper is taken from boiling water and placed into a cup filled with 38 ml of water with a
starting temperature of 21°C. After the piece of copper is placed into the cup of water, the final
temperature of the water is 32°C. Calculate the amount of energy gained by the water.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

i do not get it   at all
