Do you got the answer with you or do u have to work them out to get the answer
Answer: 2.02 J/g°C
Explanation:
To find the heat capacity, we have to manipulate the equation for heat.
q=mCΔT becomes C=q/(mΔT) to find heat capacity. Since we are given our values, we can plug in to find C.

*Please ignore the capital A in front of the °C. In order to have ° in the equaiton, the A pops up.

D. all of these can produce nuclear energy
Number of moles : n₂ = 1.775 moles
<h3>Further explanation</h3>
Given
Moles = n₁ = 1.4
Volume = V₁=22.4 L
V₂=28.4 L
Required
Moles-n₂
Solution
Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
The ratio of gas volume will be equal to the ratio of gas moles

Input the values :
n₂ = (V₂ x n₁)/V₁
n₂ = (28.4 x 1.4)/22.4
n₂ = 1.775 moles
