Question

A 8.12 g gas at the pressure of 1090 mmHg and temperature of 20oC occupies a volume of 2.00 L.  How many grams of gas is added to the same container to change the pressure to 2.00 atm. and temperature of -20oC?

Expert Solution
Step 1

Consider the given information is as follows;

Initial mass m1 = 8.12 g

Final mass m2=?                     

Amount added = ?

Initial pressure P1=1090 mmHg = 1090760=1.4342 atm             

Final pressure P2=2.00 atm

Initial temperature T1=20°C=20+273.15=293.15 K  

Final temperature T2=-20°C=-20+273.15=253.15 K

Volume of the container is constant i.e. 2.00 L
