Answer: 4.74 moles of gas are in the container.
Explanation:
1. Use the ideal gas law. PV = nRT. and re-arrange from moles by divided RT on both sides.
2.You should get the following equation: [tex]n=PV/RT[/tex]
3.Insert values: [tex]n = PV/RT = \frac{(4.9 atm)(28 L)}{(0.082 (L*atm)/(K*mol)*(353K)} = 4.74 moles.[/tex]
4.There are 4.74 moles in the container.
Good luck with chemistry!
