For a gas at 300 K, what is the RMS speed if the molar mass is 0.028 kg/mol?
500 m/s
600 m/s
700 m/s
800 m/s
Using v_rms = sqrt(3RT/M), we calculate v_rms = sqrt(3 * 8.314 * 300 / 0.028) which gives approximately 600 m/s.

Q: For a gas at 300 K, what is the RMS speed if the molar mass is 0.028 kg/mol?
Solution: Using v_rms = sqrt(3RT/M), we calculate v_rms = sqrt(3 * 8.314 * 300 / 0.028) which gives approximately 600 m/s.
Steps: 7
Step 1: Identify the formula for RMS speed, which is v_rms = sqrt(3RT/M).
Step 2: Determine the values needed for the formula: R (the gas constant) is 8.314 J/(mol·K), T (temperature) is 300 K, and M (molar mass) is 0.028 kg/mol.
Step 3: Plug the values into the formula: v_rms = sqrt(3 * 8.314 * 300 / 0.028).
