12.Kinetic Theory of Gases
normal
$27 ˚ c$ તાપમાને એક વાયુની $rms$ ઝડપ $1930 \, m/s$. છે. તો તે વાયુ.
A
${H_2}$
B
${F_2}$
C
${O_2}$
D
$C{l_2}$
Solution
${v_{rms}} = \sqrt {\frac{{3RT}}{M}} = 1930\,m/s$/ $M = \frac{{3RT}}{{{{(1930)}^2}}} = \frac{{3 \times 8.31 \times 300}}{{1930 \times 1930}} = 2 \times {10^{ – 3}}\,kg = 2\,gm$ $hydrogen.$
