Question

You have two sealed flasks, 1 and 2, of equal volume and temperature. Flask 1 contains 5.00 mol of gaseous He and flask 2 contains 5.00 mol of gaseous HF. Circle the correct answer below. a) The pressure in flask 1 is greater than/less than/equal to the pressure in flask 2. b) The velocity of the particles in flask 1 is greater than/less than/equal to the average velocity in flask 2. c) Assuming non ideal gas behavior, the intermolecular forces in flask 1 are greater than/less than/equal to the intermolecular forces in flask 2. d) The density (in g/mL) in flask 1 is greater than /less than/equal to the density in flask 2.

Explanation / Answer

a) pressure will be same in both flasks

b) avg velocity inversely proportional to molar mass

Flask -1 has more avg velocity than flask-2

c) inter molecular forces are high for HF than He

d) density = PM/RT

More molar mass , more will be density. So flask-2 has more density than flask-1
