I am having a hard time on how to get V in wavelength= h/mv
If I multiply by mv
then I get W(mv)=h
Then I get Wmv=h
I divide by Wm and get V=h/Wm
...but that doesn't seem to work.
My other question is if I am using the correct values.
W (wavelength or lamda)= 7.11x10^(-11)m
h= 6.63x10^(-34)
m= 96g
I need more help!!

change mass to kg, but shouldn't it be the mass of an electron? That is NOT 96 grams.
Thank you sooo much, I was using grams of Molybdenum, so I looked up the mass of an electron and converted it and got the correct answer. I thought I didn't solve for V right, I'm amazed that I got that right.
Thank you for your help!
