Re: Beer Lambert Law

... of serum was and and if it was a dilution that was measured. What you've calculated (almost, anyway) is the concentration (in moles per L or molarity) of NADH in the cuvette . If you really mean to calculate "micromoles per minute," like you might if you were calculating a clearance ...

Re: beer-lambert law

I expect the units of the molar absorptivity to be M^-1 * cm^-1. This will give you an answer in molarity. You'll need to convert to micromoles. Watch out for the unit mol -- I interpret that as moles. Concentration is mol/l or M. You gave the units of the molar absorptivity ...

Re: CHEMISTRY MOLARITY QUESTION

Glad to be of help. Just remember to write the balanced equation first. For the question on your final might not be a 1:1 molar ratio as it was for HCL. For example it could have been H2SO4 in which case you would have: H2SO4 + 2NaOH ----> Na2SO4 + 2H2O From the equation above you can see that 1 ...

Re: CHEMISTRY MOLARITY QUESTION

... the equation that it is a 1 to 1 mole ratio. Since you determined that .005 moles of NaOH were titrated. You now know that .005 mole HCL was used. Molarity of HCL = .005mol/.01L = .5M Our titrating HCL had a molar of .5M Now using the formula M1V1=M2V2 We have M1(.5L)=.5M(6L) transposing we get ...

CHEMISTRY MOLARITY QUESTION

... then what is the concentration of the undiluted HCL solution? This is what I thought I could do: Find the amount of moles of NaOH by using the Molarity equation. Since this is a titration and we are dealing with a strong base and a strong acid, for the solution to neutralize we need the same ...
