At 65 °C, the half-life for the first-order decomposition of N₂O₅(g) is 2.38 min.

If 1.00 g of N₂O₅ is introduced into an evacuated 15 L flask at 65 °C, 

(a) What is the initial partial pressure, in mmHg, of N₂O₅(g)?

(b) What is the partial pressure, in mmHg, of N₂O₅(g) after 2.38 min?

(c) What is the total gas pressure, in mmHg, after 2.38 min?
