PLEASE ANSWER WITH WORK!! BIG POINTS!

Using the ideal gas law, PV = nRT, in which R is always 8.31 , what pressure is required to hold 4.10 moles of nitrogen gas in a 3.2 L container at a temperature of 37 degrees Celsius? Show your work.

Multiply the volume and pressure and divide the product by the temperature and the molar gas constant to calculate moles of the hydrogen gas. In the example, the amount of hydrogen is 202,650 x 0.025 / 293.15 x 8.314472 = 2.078 moles.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
