The Ne atom has 10 times the mass of `H_(2)` molecule. Which of the following statements is true?
I. At `25^(@)C` both of them have the same kinetic energy.
II. Ten moles of `H_(2)` would have the same volume as 1 mole of Ne at same temp. and pressure.
III. One mole of Ne exerts the same pressure as one mole of `H_(2)` at STP.
IV. A `H_(2) ` molecule travels 10 times faster than Ne atom at same temperature.
V. At STP, one litre of Ne has 10 times the density of 1 litre of `H_(2).`

Options

A. II, IV, V
B. I, III, V
C. I, II, III
D. I, II

Answer

B

Explanation

K.E. is temperature dependent same moles would have same volume at same P and T
`PV=nRT`
`d=(PM_(w))/(RT)`
