Use The Thermochem Equation

#q=mcDeltat#

Where:
#q# = energy used/gained
#m# =mass of system being heated/cooled
#Deltat# =temp. change
#c# = specific heat capacity

Based on the information given, we can calculate the #Deltat#:

#Deltat# = final temp - initial temp
#Deltat = 110 - 100#
#Deltat = 10°C#

We also know that:

#m# = 346 g
#c# = 2.01 J/g°C

So we can now sub everything into our equation:

#q=mcDeltat#
#q#=(346g)(2.01J/g°C)(10°C)
#q# = 6954.6 J
