Question

The molecular mass of NADH is 709.43 Da. How many millilitres of a 50 µM solution of NADH can be prepared by dissolving 1 mg NADH?

science chemistry

Answer 1

Answer #1

mass of NADH = 1 mg

moles of NADH = 1 x 10^-3 / 709.43

= 1.41 x 10^-6 mol

concentration = 50 uM = 50 x 10^-6 M

concentration = moles / volume

50 x 10^-6 = 1.41 x 10^-6 / volume

volume = 0.02819 L

volume of NADH = 28.2 mL
