Explanation / Answer

Ans 23 : D) 630.mL

Using the ideal gas law , pV = nRT , we get the relation as :

p1V1T2 = p2V2T1

p1 = 2.42 atm

V1 = 250 mL = 0.250 L

T1 = 15oC = 288.18 K

p2 = 1.00 atm

T2 = 27oC = 300.15 K

So putting all the values :

2.42 x 0.250 x 300.15 = 1.00 x V2 x 288.15

V2 = 0.630 mL

= 630 mL
