A solution containinig the complex formed between Bi(III) andthiourea has a molar absorptivity of 9.32 x 103Lcm-1mol-1at 470nm.

a) What is the absorbance of a 6.24 x 10-5M solutionof the complex at 470nm in a 1.00cm cell?

b) What is the % transmittance of the solution described in(a)?

c) What is the molar concentration of the complex in a solutionthat has the absorbance described in (a) when measured at 470nm ina 5.00cm cell?

I have 4 more problems just like this, can you explain steps soI can do more on my own?
