Use the ideal gas law, expressed by the equation PV=nRT. The pressure, P, is 99.2 kPa. The temperature, T, is 45.0 degrees Celsius, which you must first convert to Kelvins by adding 273. The number of moles, n, is given as 0.55. The ideal gas constant, R, is approximately 8.3. Now, solve for volume, V:
99.2(V)=0.55(8.3)(45.0+273)
99.2(V)=1,451.67; V = 14.64 liters.
Use the combined gas law, PV = nRT
P = 10.634 atm
V = ?
n = 0.56 moles
R = gas constant = 0.0821 L-atm/deg-mole
T = 65ºC +273 = 338ºK
V = nRT/P = (0.56)(0.0821)(338)/10.634 atm
V = 1.46 liters = 1.5 liters (2 sig figs)
PV = nRT
P = Pressure (Pascals)
V = Volume
n = Number of Moles
R = Ideal Gas Constant
T = Temperature (K)

I would assume chlorine gas and standard temperature an atmospheric pressure. Using the ideal gas equation. PV = nRT (1 atm)(X volume) = (2.4 moles Cl2)(0.08206 Mol*K/L*atm)(298.15 K) Volume = 59 Liters of chlorine gas --------------------------------------------
First we need the moles of krypton gas. Monoatomic gas.0.405 grams Kr (1 mole Kr/83.80 grams)= 0.004833 moles krypton gas======================Now the ideal gas equation.PV = nRT(1 atm)(X volume) = (0.004833 moles Kr)(0.08206 L*atm/mol*K)(298.15 K)= 0.118 Liters of krypton gas--------------------------------------

Pressure, volume and temperature, and moles of gas are the four principal variables to describe a gas (for example, see related questions on Ideal Gas Law and others). The standard units are: Pressure: atmospheres (atm) Volume: liters (L) Temperature: Kelvin (K) Number of moles are measure in, well, moles.
First find moles hydrogen gas. 20 grams H2 (1 mole H2/2.016 grams) = 9.921 moles H2 Now, the ideal gas equation. PV = nRT (1 atm)(volume L) = (9.921 moles H2)(0.08206 L*atm/mol*K)(298.15 K) Volume of hydrogen gas = 243 Liters ----------------------------------------------------
Three variables that effect volume (V) of gas are pressure (P), temperature (T), and how many moles (n) of gas are present in a system. Decreasing any of these variables correspond to gas volume reductions. These can be related by the Ideal Gas Law equation of PV = nRT. R is the Ideal Gas constant of .0821 Liters/ATM*moles*Kelvin.
You solve this using the ideal gas law: PV = nRT and solve for n (moles)n = PV/RT = (2.62 atm)(47.8 L)/(0.0821 Latm/Kmol)(775K) n = 1.97 moles (3 significant figures)
