Question

5. If a sample of gas occupies 6.80 L at 325°C, what will its volume be at 25°C? 6. A gas at 155 kPa and 25°C has an initial volume of 1.00 L. What will the volume be at STP? 7. A sample of neon has a volume of 345 mL at 25°C and 90 kPa. Calculate moles. 8. What volume is occupied by 0.250 g CO, at 25°C and 80.5 kPa? 9. At 46°C and 89 kPa pressure, a gas occupies a volume of 0.600 L. How many liters will it occupy at 0°C and 20.8 kPa?

Answer 1

6 Initial state Volume (vi)=6.82 Temporature (11) = 1325+273) K. = 598k final state. volume (V2) = ? Temperature (Iz) – 65+273)* 52983 Now, where a vz = * 6-8x298 lit 598 = 3.389 lit. So the volume at 25°c will be [3:389) lif
