A sample of gas occupies 135 mL at 22.5 C; the pressure is 165 mm Hg. What is the pressure of the gas sample when it is placed in a 252-mL flask at a temperature of 0.0 C?
pressure of gas sample___________________ mmHg
Ethane, C2H6, burns in air according to the equation
2C2H6(g) 7 O2(g)---->4CO2(g) + 6H2O(g)
What volume of O2 (in L) is required for complete reaction with 5.2L of C2H6? What volume of H2O vapor
(in L) is produced? Assume all gases are measured at the same temperature and pressure?
volume of O2____________________L
volume of H2O vapor_______________L© BrainMass Inc. brainmass.com November 24, 2022, 11:42 am ad1c9bdddf

Q-1 From the formula of ideal gas law, PV=nRT, you can deduce the below formula. P1, V1 and T1 are for the first condition and P2, V2 and T2 are for the second condition.
P1 * V1 P2 * V2
The solution is given in an attachment with short explanations.
