2. Count its valence electrons.
3. Add one electron for each bonding atom.
4. Add or subtract electrons for charge
5. Divide the total of these by 2 to find the total.
number of electron pairs.
6. Use this number to predict the shape.

Answer : The molar heat capacity at constant volume and constant pressure is 29.9 J/mol.K and 38.2 J/mol.K respectively.
Explanation :
Formula used for specific heat at constant volume :
where,
= heat = 229 J
n = moles of gas = 3.0 mol
= molar heat capacity at constant volume = ?
= change in temperature = 2.55 K
Now put all the given value in the above formula, we get:
The molar heat capacity at constant volume is 29.9 J/mol.K
Now we have to calculate the molar heat capacity at constant pressure.
Formula used :
where,
= molar heat capacity at constant volume = 29.9 J/mol.K
= molar heat capacity at constant pressure = ?
R = gas constant = 8.314 J/mol.K
Now put all the given value in the above formula, we get:
The molar heat capacity at constant pressure is 38.2 J/mol.K
