I'm stuck on this assignment, +20 PTS and BRAINLIEST for step by step:
Assume constant n and T for questions 2; P1V1 = P2V2
2. If the pressure exerted on the gas in a 3.05-L balloon changes from 870 kPa to 969 kPa, what will be the new volume of the balloon?
Assume constant n and P for questions 3 & 4; V1/T1 = V2/T2
3. A sample of neon gas occupies 3.32 L at 360K. At what temperature would the volume of this sample of neon be at 4.50 L?
4. If 5.10 L of an ideal gas is cooled from -56°C to -82°C, what will be the new volume of the gas?
Assume constant P and T for questions 5 & 6: V1/n1 = V2/n2
5. If 0.750 mol of an ideal gas occupies a volume of 37.2 L at a particular temperature and pressure, what volume will 0.778 mol of an ideal gas occupy under the same conditions?
6. If 2.65 mol of an argon gas occupies a volume of 86.0 L at a particular temperature and pressure, how many moles would occupy a volume of 92.5 L under the same conditions?
Assume constant n and V for questions 7 & 8; P1/T1 = P2/T2
7. A sample of air exerts a pressure of 3.00 atm at 390K. To what temperature must the air be cooled so that it exerts a pressure of 2.45 atm?
8. A sample of helium in a rigid container exerts a pressure of 3.00 kPa at -12.3°C. What pressure will the helium exert if the temperature is changed to 25°C?
