If equal masses of oxygen and nitrogen are placed in separate containers of equal volume at the same temperature, which one of the following statements is true ?(Mol wt. N_2=28, O_2=32)

Answer»

<P>Both flasks contain the same number of molecules
The pressure in the nitrogen FLASK is greater than in the oxygen flask.
More molecules are present in the oxygen flask
Molecules in the oxygen flask are moving FASTER on the average than the ones in the nitrogen flask

Solution :`PV=nRT implies P=(nRT)/V implies n_(N_2)gtn_(O_2)implies P_(N_2)gtP_(O_2)`
