Any good pharmacy students here? Please can you help with this problem?

The fluorescence of a quinine solution 0.1 ugcm-3 was measured in the presence of various concentrations of bromide ion. Use the data below to calculate the quenching constant for the quenching of quinine florescence with bromide.

10 to the power 3
/ mol dm-3 0.0 2.0 5.0 11.0 18.0 25.0
fluorescence 77 38 26 15 10 7.6
How about going to the library and reading up on quenching calculations?
It's simpler than you think

OMG I so cant do this question, and I've been qualified for 13 years, did a PhD and was then a lecturer. What ARE they teaching you these days?
