At room temperature a diatomic gas is found to have an r.m.s. speed of $1930 ms^{- 1}$ . The gas is:

Options:

Answer:

Solution:

$∵ C = \frac{3 RT}{M} (193 0^{2}) = \frac{3 \times 8.314 \times 300}{M} M = \frac{3 \times 8.314 \times 300}{1930 \times 1930} \approx 2 \times 1 0^{- 3} kg$ The gas is $H_{2}$ .
