210 cm^3  of Nitrogen at a pressure of 400 mmHg  and 100 cm^3  of carbon(iv)oxide at a pressure   of 350 mmHg were introduce into a 200 cm^3   vessel. what is the total pressure in the vessel.

The total pressure is  P_(total) =((P_1 V_1 +P_2 V_2 )/(V_1 +V_2 ))               =((400×200+350×100)/(200+100))               =((800+350)/3)=((1150)/3)≈383.3333mmHg
$$\mathrm{The}\:\mathrm{total}\:\mathrm{pressure}\:\mathrm{is} \\ $$$$\mathrm{P}_{\mathrm{total}} =\frac{\mathrm{P}_{\mathrm{1}} \mathrm{V}_{\mathrm{1}} +\mathrm{P}_{\mathrm{2}} \mathrm{V}_{\mathrm{2}} }{\mathrm{V}_{\mathrm{1}} +\mathrm{V}_{\mathrm{2}} } \\ $$$$\:\:\:\:\:\:\:\:\:\:\:\:\:=\frac{\mathrm{400}×\mathrm{200}+\mathrm{350}×\mathrm{100}}{\mathrm{200}+\mathrm{100}} \\ $$$$\:\:\:\:\:\:\:\:\:\:\:\:\:=\frac{\mathrm{800}+\mathrm{350}}{\mathrm{3}}=\frac{\mathrm{1150}}{\mathrm{3}}\approx\mathrm{383}.\mathrm{3333mmHg} \\ $$
