Answer:

0.0146cm^3

Explanation:

Using the combined Gas Law P1V1/t1 = P2V2 /t2

P1.. 0.934

V1..0.0148

T1..11° ( 284K)

P2 =0.974

V2= V2 (unknown)

T2= 20° (293K)

Hence 0.934x 0.0148 / 284 = 0.974x V2 / 293

0.000048= 0.974V2 /293

0.000048 x 293 = 0.974V2

0.01426=0.974V2

V2 = 0.01426/ 0.974

V2 = 0.0146 cm^3
