Question

896 mL of a mixture of CO and Co, weigh 1.28 g
at NTP. Calculate the volume of Co, in the mixture
at NTP. ANS. 224ml​

Answer 1

Answer:

Answer: 224 ml

Explanation: Let's assume 'x' ml CO2

and hence '896-x' ml CO.

Also assume 'y' g CO2

and hence '1.28-y' g CO.

by equating moles of CO2 i.e.

x/22400= y/44

and by equating moles of CO i.e.

896-x/22400 = 1.28-y/28

now by solving the two equations two variables we get y=11/25 and therefore x= 224 ml.
