If i have 4 moles of a gas ata pressure of 5.2 atm and a volume of 15 liters, what is the temperature?
kompoz [17]

Answer:

237.5 K.

Explanation:

  • We can use the general law of ideal gas: <em>PV = nRT. </em>

where, P is the pressure of the gas in atm (P = 5.2 atm).  

V is the volume of the gas in L (V = 15.0 L).  

n is the no. of moles of the gas in mol (n = 4.0 mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),  

T is the temperature of the gas in K (T = ??? K).

∴ T = PV/nR = (5.2 atm)(15.0 L)/(4.0 mol)(0.0821 L.atm/mol.K) = 237.5 K.
