A94 l sample of neon gas (molar mass= 20.2 g/mol) has a mass of 44 g at a pressure of 150 kpa. what is its temperature in kelvins?

778.96 K.

Explanation:

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant (R = 0.082 L.atm/mol.K),

T is the temperature of the gas in K.

The temperature of the gas = PV/nR.

P = 150.0 kPa/101.325 = 1.48 atm, V = 94.0 L, R = 0.082 L.atm/mol.K, n = mass/molar mass = (44.0 g)/(20.2 g/mol) = 2.178 mol.

∴ T = PV/nR = (1.48 atm)(94.0 L)/(2.178 mol)(0.082 L.atm/mol.K) = 778.96 K.

where is the following

explanation:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
