id hate to lose points this early in the game over such an introductory problem

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

this is stuff we learned 2 years ago, im just looking for a "that's affirm" on the quiz being bogus

Luke de Spa · 08-27-2006, 06:32 PM

shouldn't the correct answer be to two decimal places

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

?
