The pressure of a 5.00 L flask at 25˚ C that contains 0.200 mol of Cl2 is 0.98atm.
<h3>How to calculate pressure?</h3>
The pressure of a gas can be calculated by using the following expression:
PV = nRT
Where;
- P = pressure
- V = volume
- n = number of moles
- R = gas law constant
- T = temperature
P × 5 = 0.2 × 0.0821 × 298
5P = 4.893
P = 4.893 ÷ 5
P = 0.98atm
Therefore, the pressure of a 5.00 L flask at 25˚ C that contains 0.200 mol of Cl2 is 0.98atm.

Choice ' D ' is the correct statement.
Probably A, since it’s the only covalent compound. The rest are ionic compounds.
