I'd say you should study and if you cant figure this shit out yourself then you should switch majors

moles of signal = 3.9867 x 10^-23 mol

V = pi x 0.000005cm x 0.000005cm x 0.000088cm
V = 6.9115 x 10^-15 cubic cm
/ 1000
V = 6.9115 x 10^-18 litres

3.9867 x 10^-23 mol / 6.9115 x 10^-18 litres
= 0.5768 x 10^-5
= 0.000005768 M
= 5768 nM

?
