### question 1.41

For hw question 1.41 , I used debrogile equation, however I was confused on the mass of a neutron, it isn't given , so is this common information we need to know ? If so I didn't know which mass of a neutron to use as the internet had different amounts for the neutron I found 1.6749 x 10-27 kg. do i have to convert it to grams, is this the correct amount ?

information like that will be provided on the test. SI unit for mass is kg.
