Question

HELP, MEDAL & FAN: A sample of gas occupies 6.1 L at a pressure of 102 kPa. What volume will it occupy if the pressure is increased to 230 kPa? Round your answer to two decimal places.

I'd like someone to walk this through with me and not just an answer. Thanks. :)

Answer 1

Any ideas?

Answer 2

$$P_1*V_1=P_2*V_2$$

Answer 3

394 kPa or 1725 kPa

Answer 4

Have you worked with that^ formula before? :-)

Answer 5

yes

Answer 6

yes

Answer 7

I have that in my notes, but I'm confused after setting the problem up

Answer 8

The question asks for volume @Greenbay12 not pressure :-)

Answer 9

Solve for V sub 2 by dividing both sides by 230.

Answer 10

(6.1*102)/230

Answer 11

solving for v1 or 2

Answer 12

?

Answer 13

The question asks for the answer rounded to two decimal places :-)

Answer 14

In the formula "1" means the initial conditions. The "2" means the final conditions.

Answer 15

oh ok

Answer 16

6.1 = initial volume

102 = initial pressure

Answer 17

They use "1" because one comes before two :-)

Answer 18

so then v2=2.71?

Answer 19

Don't forget the units of measurement.

Answer 20

2.71 L

Answer 21

Good job
:D

Answer 22

Thanks! :)
