"You're creating a standard curve for pyruvate. You need to create a standard with 20 micromoles in a cuvette. How much 100 mM pyruvate would you need?"
My understanding is to solve for VOLUME using the equation:
micromoles = (mM)(volume in ml)
20 micromoles = (100mM)(x)
Solve for x
x = 0.2mL
Am I on the right track?
