Question

The pressure of 2.91 mol of gas in a rigid tank is 772 kPa. What is the pressure if an additional 4.00 mol of gas is ADDED to the tank? Assume the temperature and volume are constant.

Answer 1

Step-by-step explanation:

For every 2.91 moles the pressure is 772 kpa:

(4.00 + 2.91 ) / 2.91 * 772 = 1830 kpa ( using three significant digits)
