Can somebody help me with this Quantitative Analysis Chemistry problems, I need this tonight and I keep getting the wrong answers.

1) Two absorption peaks located near 250 nm are separated by 0.02 nm. What minimum resolution must a grating have in order to separate these wavelengths?

2)Two absorption peaks located near 250 nm are separated by 0.04 nm. How many grooves must a grating have to separate these two peaks in ord)er number 3?

3) A single FTIR scan yielded a spectrum with a signal-to-noise ratio of 8. What should the signal-to-noise ratio be for a spectrum obtained by signal averaging 7500 scans?
