A 3.00-L rigid container is filled with N2(g) at 59.0C. A 1.245 g gas sample of acetone, CH3(CO)CH3, is then added. The total pressue is 430.00 torr. Assuming no N2(g) leaks out during the addition and the temperature stays constant, calculate the partial pressue of nitrogen? What is the initial pressue of nitrogen?
