Answer:

10220.9T (to 6 sig' fig's)

Explanation:

PV = nRT ← Ideal Gas Equation

(5.4862)(89.148) = n(8.31)(190.21 + 273)

489.08.... = 3849.2...(n)

n = 0.127....

P(36.367) = (0.127....)(8.31)(463.21)

36.367(P) = 489.08....

P = 13.448.... atm's

And since 1 atm = 760 Torr,

P = 13.448... × 760

P = 10220.9051 T (→ 10220.9 T)
