**Sun Nov 03, 2019 8:27 pm**(Problem: A new element GarBreadium is discovered to have molar mass 3.157 g∙mol-1. The GarBreadium atom travels at an average speed of 1.35x103 m∙s-1 at room temperature. What is the average wavelength of the GarBreadium atom at room temperature?)

My answer for this problem comes out to 9.36x10^-14 m, but the answer key says the answer is 9.36x10^-11 m. I'm using p=mv and λ=h/p to solve this problem. I can't see why my power of 10 is wrong. Can anyone explain?
