Question

Assuming ideal gas behavior, what is the total pressure exerted by a mixture of 0.50 mol of CH_4 and 2.0 mol of H_2 in a 5.0 L container at 25 degreeC? 1.0 atm 12 atm 21 atm 39 atm Conersion of a solid directly into a glass is called evaporation boiling melting sublimation A real gas condenses to a liquid at low temperature as a result of the very small molecular volume presence of intermolecular forces. smaller diffusion rates at lower temperatures. lower vapor pressure of the liquid. The unit cell of a diamond can be viewed as a face-centered cubic lattice with four additional carbon atoms in a unit cell is

Explanation / Answer

10.

If idea gas, then this is valid

n total = 0.5+2 = 2.5 mol

the ideal gas law is PV = nRT

solving for Pressure

P = nRT/V

P = (2.5*0.082)(298)/5 = 12.218 atm

nearest answer is 12 atm
