Homework Statement
I have worked these two problems to the best of my knowledge and I keep getting the wrong answer (I'm not sure what the right answer is). Here are the questions:
1. At a certain temperature the solubility of barium chromate (BaCrO4) is 1.9×10-5 mol/L. What is the Ksp of...
I think I figured it out. I think my instructor made a mistake on this. I believe the answer should be 1.10 x 10^7 m^-1 and not 1.10 x 10^-7 m^-1. After calculating the normal equation constants, this is what I came up with.
1/wavelength = (2.18 x 10^-18 J / ((6.63 x 10^-34 J x s)(3.00 x 10^8...
Ok, I see what you mean. At the end, I should have done (for number one) R = 0.0096178758 nm^-1 x (1 x 10^9 nm/1 m) which results in 9.6178759 x 10^6 m^-1. My answer is even more off. I tried this with my instructor's value to see if I get the correct answer. I did 1/675 nm = R ((1/2^2) -...
Homework Statement
For our lab, we looked through the spectrometer to find the spectral values for Helium, which after being plugged into an excel spreadsheet, yielded an equation which I could use to find the wavelengths for Hydrogen. We were told to solve for R, which I did. However, at the...
