The average speed of oxygen molecules in air is about ____. (1 point) 0 km/h 170 km/h 1700 km/h 17,000 km/h

LenKa [72]

The average speed is calculated using the following formula $speed = \sqrt{\frac{3kT}{m} }$

Where

$k = 1.381 X 10^{-23} J / K$

T = 298 K [room temperature]

m = mass of each molecule of oxygen

mass of one mole of oxygen molecules = 32 g / mol

mass of one molecule of oxygen will be = $\frac{32}{6.023 X 10^{23} }$

mass of one molecule of oxygen will be = $5.31 X 10^{-23} g = 5.31 X 10^{-26} kg$

putting values

average speed = $\sqrt{\frac{3 X 1.381 X 10^{-23} X 298}{5.31 X 10^{-26} kg} }$

Average speed = 482.19 m / s

average speed = 1735.8 km / h

so approx = 1700 km/h
