Question

A sample of methane (CH4) has a volume of 29 mL at a pressure of 0.88 atm . What is the final volume, in milliliters, of the gas at each of the following pressures, if there is no change in temperature and amount of gas?

A.)

2600 mmHg

Express your answer using two significant figures.

B.)

86.0 torr

Express your answer using two significant figures.

Answer 1

0 Initial final - 0.88 atm x qamL P=0.88 atm B = 2600 mm Hg V=29mL 1 V₂=ml Temp constant TPV=PLv2 H o u= Pivi - 2 P2 2600 atre. 760 Volume (V2) = 7.40 ml Tvolume (V2) = 704 mL From ear . PIVI 0.88 atm x 29 mL V₂ = PR 786 atm 86 760 Volume (2) 3 225.52 ml volume v2=2+2 x 10 ml
