@Preetha help?

Answer 2

use PV=RT formula

Answer 3

or, PV=nRT

P=nRT/V

Answer 4

please help me though go through the steps ? @sriramkumar

Answer 5

For the first one how would you set it up? P = pressure right? V = volume? & n = moles? and R = what? & T = temperature

Answer 6

here n=0.75 V=40.5 T=19+273 = 292 R=0.0821 substitue to get the answer :D

Answer 7

Can you help me set up the first one please? (: I would really appreciate it ! THANK YOU!! @sriramkumar

Answer 8

Nvm I got 6.0 for the first one thats right right?

Answer 9

Could you just help me on this last one?

Answer 10

use it as PV1=n1RT PV2=n2RT now V1/V2 = n1/n2

given V1=2 n1=0.1 n2=0.10 + 0.40 = 0.5 substitue and you'll get to the answer :D
