A reaction between liquid reactants takes place at -8.0 C in a sealed, evacuated vessel with a measured volume of 10.0 L. Measurements show that the reaction produced 12 g or carbon dioxide gas. Calculate the pressure of carbon dioxide in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round you answer to 2 significant digits.

Answer : The pressure of carbon dioxide in the reaction vessel after the reaction is, 0.59 atm.

Explanation : Given,

Mass of = 12 g

Molar mass of = 44 g/mol

First we have to calculate the moles of carbon dioxide gas.

Now we have to calculate the pressure of carbon dioxide gas.

Using ideal gas equation:

where,

P = pressure of gas = ?

V = volume of gas = 10.0 L

n = number moles of gas = 0.273 mol

R = gas constant = 0.0821 L.atm/mol.K

T = temperature of gas =

Now put all the given values in the above formula, we get:

Therefore, the pressure of carbon dioxide in the reaction vessel after the reaction is, 0.59 atm.
