Question #742bc

Answer 1

b. 120'K

Explanation:

Start with the Ideal Gas Law: `P*V = (n*R*T)`
Rearranging the Ideal Gas Law equation we have `T = (P*V)/(n*R)`

V = 100.0 L
R = 0.0820575 L-atm/K-mol
28kg = 28000g
n = (28000g/28.0 g/mol) = 1000 moles of `N_2`.
`P = (1 x 10^7 Pa) * ((1 "atm")/101325 Pa)` = 98.7 atm
`T = (98.7*100)/(0.0821*1000)` = 120 ‘K
