Question

A gas occopies 100cc at 340 mmHg. what is its volume at 100 mmahg assuming temperature to be constant

Answer 1

Explanation:

ANSWER

Initial temperature T

1

=0

o

C=273.15K

Initial pressure P

1

=1atm

Initial volume V

1

=100cc

Final temperature T

2

=(1+

)×273.15=364.2K

Final pressure P

1atm×100cc

=

364.2K

1.5atm×V

=88.9cc

Hence, the final volume of the gas will be 88.9 cc.

Therefore, the correct option is A.
