### Homework Problem(s)

I was having trouble with a few problems from Chapter 1 (such as 1.41. and 1.37). Both involved using the mass of either a proton, neutron, or both. Are we suppose to already know the mass of a proton or a neutron? (It wasn't given in the question.)

Those masses would be given to us on a test.

I believe the masses would be given on the tests. You can even see the sheet given on Test 1 which was passed back last week

### Re: Homework Problem(s)

I was needing help on question 1.13 part B in which it asks "What is the name given to the spectroscopic series to which this transition belongs?" The answer being 2.8x10^-7 m or 2.8x10^9 nm. Can someone answer me to what series it is and why?

For 1.13 part A I got 486 nm. For part B, a wavelength of 486 nanometers tells us that it is in the visible light region and is therefore part of the Balmer series (remember the Balmer series uses n =2 and is in the visible light region). I am not sure what answers you are talking about.

The masses of these will be given on equation sheet.

### Re: Homework Problem(s)

The masses of both of these will be on the equation sheet.
