My experimental data must have been wrong..What I've calculated is 100% right.

I actually figured it out... Here's my work: a. R((1/2^2)-(1/3^2)) = .00152 = 1/.00152 = 657.89 nm b. R((1/2^2)-(1/4^2)) = .00205 = 1/.00205 = 487.80 nm c. R((1/2^2)-(1/5^2)) = .00230 = 1/.00230 = 434.78 nm d. R((1/2^2)-(1/6^2)) = .00243 = 1/.00243 = 410.21 nm

There's no way to predict that..Here's what I'm thinking is right: 1/pi = R(1/nf - 1/ni) R = 109737 cm nf = 750 nm = 7.5*10^-5 CM ni = 490 nm = 4.9*10^10-9 CM So... 1/pi = 109737 (1/(7.5*10^-5) - 1/(4.9*10^-9)) = 1/pi = -2.23*10^13 UGHhhh...what the heck! I JUST DONT GET...

Bump. I've figured everything out. But can't still solve this question: "Using the Rhydberg equation, calculate the transitions in the H-atom that are taking place to give rise to each line." If you look at my data, it has 7 lines...Shouldn't I just be calculating it from the highest line I...

Homework Statement I'm just curious to if I have answered this questions properly, and was wondering if someone can see if I should add more to what I have written, or completely change my answer. I'm pretty confident with what I've answered, but would like someone to check :) So to begin...

Hmmm...your work seems right to me. maybe you typed it wrong?

Wow, so 7.74 cm^2 is what I'm getting. Thanks for the help guys. I definitely won't forget my units this time xD But yeah, I got 7.74 cm^2.

1. Convert 1.2 in^2 to cm^2 2. 1 CM = 10^-2 and 1 inch = 2.54 centimeteres The Attempt at a Solution Can't we just do 1.2*2.54=3.048 and write that as our answer?

Just curious, but why are we dividing by 10? FYI, I'm taking the temperature in Fahrenheit.

For the following data set of eight values, give the MEAN, DEVIATION (DEV), and AVERAGE DEVIATION (AD). Show a sample calculation for each: 0.77, 0.92, 1.12, 1.00, 0.96, 0.88, 1.16, 1.02 Homework Equations Well before we began, can anyone take the courtesy and see if I'm getting the...

Thanks, I was right :) I even asked the teacher, he confirmed it. Also, there's this odd question... "What does it mean when you a piece of glassware that is "graduated" or has "graduations" on it?" Couldn't we describe graduations as precise measuring marks?

I'm curious if I'm doing this chemistry lab correctly or not. If you open the link below, you can see the lab. Basically, my job right now is to write a well formulated procedure on how to perform this lab. So, for this lab, am I supposed to be calculating the mass of the substance (h2o in...

Homework Statement Assume that Earth’s magnetic field is everywhere perpendicular to the path of a proton and that Earth’s magnetic field has an intensity of 4.07 × 10−8 T. What speed would a proton need to achieve in order to circle Earth 1660.0 km above the magnetic equator? Answer...

:o, thanks a ton man. I think this was a trick question...Since I never thought of the diameter. It makes sense why its 26.7-18 instead of 9. Thanks for clearing it up, I was really starting to get a little confused there.

I don't understand what you mean lol. It doesn't give us a mass. So why use mass in the equation when not even all of them cancel out. How am I supposed to solve it with that equation. I'm confused xD
