Question

50. A bulb of unknown volume contained an
ideal gas at 650mm pressure. A certain amount
of the gas was withdrawn and found to occupy
1.5 c.c at 700mm pressure. The pressure of
the gas remaining in the bulb was found to be!
600mm.If all measurements are made at the
same temperature, the volume of the bulb is
1) 21 c.c 2) 42 c. 3) 105 c.c 4) 63 c.c​

Answer 1

Answer:

The equation can be expressed as

$P_{1} V_{1} =P_{2} V_{2}$

650V=700*(V+1.5)

650V=700V+1050

50V=1050

V=21cc

so option 1 is correct

Answer 2
