Two flasks A and B of 1 L capacity each contain `SO_(2)` and `Br_(2)` gases respectively maintained at 340 K and pressure of 1.5 atmosphere. If number of `Br_(2)` molecules in flask I is N, the total number of atoms in flask A will be

Options

A. N
B. 2N
C. `N//2`
D. 3N

Answer

D

Explanation

Number of `SO_(2)` molecules in flask `A =` Number of `Br_(2)` molecules in flask `B = N`
Number of atoms in N molecules of `SO_(2) = 3 xx N = 3N`
