Answer 1

A)

Given:

P2 = 0.64 atm

P1 = 1.11 atm

V2 = 0.67 L

T2 = 41.8 oC

= (41.8+273) K

= 314.8 K

T1 = 3.1 oC

= (3.1+273) K

= 276.1 K

use:

(P2*V2)/(T2) = (P1*V1)/(T1)

(0.64 atm*0.67 L)/(314.8 K) = (1.11 atm*V1)/(276.1 K)

V1 = 0.339 L

Answer: 0.339 L

B)

Given:

P2 = 629 torr

P1 = 126 torr

V2 = 36.0 mL

V1 = 41.3 mL

T2 = 209.0 K

use:

(P2*V2)/(T2) = (P1*V1)/(T1)

(629 torr*36 mL)/(209.0 K) = (126 torr*41.3 mL)/(T1)

T1 = 48.0 K

Answer: 48.0 K

C)

Given:

P2 = 0.402 atm

V2 = 2.02 L

V1 = 1.875 L

T2 = 47.3 oC

= (47.3+273) K

= 320.3 K

T1 = 21.4 oC

= (21.4+273) K

= 294.4 K

use:

(P2*V2)/(T2) = (P1*V1)/(T1)

(0.402 atm*2.02 L)/(320.3 K) = (P1*1.875 L)/(294.4 K)

P1 = 0.3981 atm

Answer: 0.398 atm
