The ground state electron configuration of ground state gaseous neutral antimony is [Kr].4d10.5s2.5p3
Answer:
n = 1.48 mol/s
Explanation:
ideal gas:
⇒ n = PV/RT
∴ T = 1.60 E2 °C = 160°C = 433 K
∴ R = 0.082 atm.L/K.mol
∴ P = 49.3 psig * ( atm/ 14.6959psig ) = 3.35 atm
∴ V = 940 L/min
⇒ n = (( 3.35 )*( 940 )) / (( 0.082 )*( 433 ))
⇒ n = 88.813 mol/min * ( min / 60s )
⇒ n = 1.48 mol/s
