This problem is providing us with the mass (70 g), absorbed heat (96 J) and initial and final temperatures (293 K and 313 K, respectively) so the specific heat of the material is required and found to be 0.0686 J/(g*K) as shown below:
<h3>Calorimetry:</h3>
In chemistry, we can go over calorimetry by writing the following relationship among heat, mass, specific heat and temperature change:
Thus, one can get the specific heat by solving for C in the previous equation:
Hence, we can plug in the given data to obtain:

Answer:
The ratio of the temperature of helium to that of hydrogen gas is 2:1.
Explanation:
Atomic mass of hydrogen = M
Temperature of hydrogen gas =T
Pressure of the hydrogen gas = P
Mass of the hydrogen gas = m
Moles of the hydrogen gas =
Volume of the hydrogen gas = V
Using an ideal gas equation:
...(1)
Temperature of helium gas =T'
Pressure of the helium gas = P'= P
Mass of the helium gas = m' =m
Moles of the helium gas =
Volume of the helium gas = V' = V
Using an ideal gas equation:
...(2)
Divide (2) by (1)
The ratio of the temperature of helium to that of hydrogen gas is 2:1.
