Concept explainers
Interpretation:
Volume of dry gas at STP has to be determined.
Concept Introduction:
Ideal gas is hypothetical or theoretical gas that is formed from large number of randomly moving particles with perfectly elastic collisions between them. This gas is considered to follow
The formula for ideal gas equation is as follows:
Here,
Answer to Problem 14PQ
Option (B) is the correct one.
Explanation of Solution
Reason for correct option:
For gas at temperature
Here,
For gas at temperature
Here,
Divide equation (1) by equation (2) as follows:
Rearrange equation (4) to calculate
Temperatures are to be converted into
Therefore, value of
Therefore,
Conversion of pressure from
Therefore, value of
The pressure of dry gas
Substitute
Hence option (B) is correct.
Reason for incorrect option:
Volume of dry gas becomes
Volume of dry gas at STP is
