First, we need to convert the temperature from Celsius to Kelvin:
27.0°C + 273.15 = 300.15 K
Next, we can use the formula for root mean speed:
u rms = √(3RT/M)
where R is the gas constant, T is the temperature in Kelvin, and M is the molar mass of the gas.
Plugging in the values:
u rms = √(3 * 8.314 * 300.15/0.032)
u rms = 482.8 m/s (rounded to three significant figures)
Therefore, the root mean speed of oxygen gas, O2, at 27.0°C is approximately 482.8 m/s.
Calculate the root mean speed of oxygen gas O2 at 27.0 oC. (R=8.314 Kg.m3/s2.K.mol)
(Molar mass: O= 16 g/mol)
