Calculating the Momentum of Oxygen Molecules at 484 m/s

[Punkyc7]

What is the momentum of an oxygen molecule traveling at this speed?

the speed was 484 m/s

the molar mass of oxygen is M=.032 kg/mole

Na= 6.022 x10^23
I do p=mv

v=484
m=M/Na

The answer should be 2.57x10^-13 but i keep getting 2.57 x10^-23

Check your calculations again, your operations are correct.

I still get 2.57 x 10^-23
