Reaction 1:

20 moles of Sodium bicarbonate is heated to 752°F. Now, whole of $CO_2$ evolved in the reaction is stored in 1L container A.

Reaction 2:

Now, 2000L solution of 2 pH HCl is reacted with Sodium carbonate released in reaction 1. Now, whole of $CO_2$ evolved in this reaction is added to same container A (In which Carbon dioxide released in reaction 1 was stored)

Now, What in the pressure in container A assuming ideal gas behaviour and taking temperature in container as 27°C . (Take value of gas constant as 0.0821)

Give answer in atmosphere unit
