Web13 Apr 2024 · Taking the square root, we get: v r m s = 1.845 × 10 3. Hence, the root mean square velocity of hydrogen molecules at STP is 1.845 × 10 3 m s − 1. Additional Information: We can solve this problem using another method. Use the formula P V = n R T to substitute R T by P V n and take the values of pressure and volume at STP (take … WebCalculate the root mean square velocity for the atoms in a sample of oxygen gas at 32u0001°C. Solution: Use the equation for room mean square velocity. M must be expressed in kilograms, so M for O 2 equals 0.032 kg/mol We must also convert 32°C to Kelvin. 32 + 273 = 305 K Plugging in these values into the formula, we get Problems 1.
