Question
ANSWER ONLY FIVE OF THE FOLLOWING SEVEN QUE3 WORK (calculations)NOT ONLY ANSWER 1 Avoume ofcarbon dioxide gas,CO, equal to 20.0 L. was colected at 23 o C and 1 atm pressure What would be the volume of carbon dioxide collected at 23C and 0.830 atm? 2 Vihat is the pressure in a so 0-4 gas cylinder that contains 3,.03 kg of oxygen, Oa. at 23°c? 3. A 0200-L flask contains 1.03 mg oxygen,O2 and o.56 mg helium,He at 15°C.Calculate the part pressure of axygen and helium in the flask. What is the total pressure? 4. What is the ratio of rates of effusion of nitrogen, N2 and oxygen, O2 under same conditions?Explanation / Answer
Ans1:
Volume of CO2 collected V1 = 20.0 lt
Temperature of collection T1 = 23oC
Pressure of collection P1 = 1atm
Volume of CO2 collected V2 = ? lt
Temperature of collection T2 = 23oC
Pressure of collection P2 = 0.830atm
We know, at constant temperature, P1V1 = P2V2
=> 1*20 = 0.830*V2
=> V2 = 24.1 lt
Therefore volume of carbondioxide 24.1lt
