SUMMARY
The momentum of an oxygen molecule traveling at a speed of 484 m/s is calculated using the formula p=mv, where the molar mass of oxygen (M) is 0.032 kg/mole and Avogadro's number (Na) is 6.022 x 10^23. The correct mass (m) of a single oxygen molecule is derived as M/Na, leading to a momentum value of 2.57 x 10^-13 kg·m/s. The confusion arose from a miscalculation that resulted in an incorrect value of 2.57 x 10^-23, which was clarified as erroneous.
