Answer:
[tex]T = 1.26 \times 10^8 K[/tex]
Explanation:
As we know that rms speed of ideal gas is given by the formula
[tex]v_{rms} = \sqrt{\frac{3RT}{M}}[/tex]
here we know that
[tex]v_{rms} = 2.67 \times 10^5 m/s[/tex]
molecular mass of gas is given as
[tex]M = 44 g/mol = 0.044 kg/mol[/tex]
now from above formula we have
[tex]2.67\times 10^5 = \sqrt{\frac{3(8.31)T}{0.044}}[/tex]
now we have
[tex]T = 1.26 \times 10^8 K[/tex]
