Answer:
784 torr
Explanation:
Using Pressure Law; at constant volume,
P∝ T at constant volume.
P= kT ; meaning
P1/T1 = P2/T2
P1= 758 torr
P2= ?
T1= 21 ° C or (273+21)K
= 294°K
T2= 31 ° C or (273+31)K
= 304°K
Substituting into equation (1),
We have:
758/294 = P2/304
P2 = 758 x 304/294
= 783.78torr
≈ 784 torr
