Question

You are given a food containing 6 g protein per serving (30g), how much of the food you needto add to 100 ml solution to make a solution with 500 μg protein/ml? What is the dilution factor?

Answer 1

Hey there!

500 mg of protein is present in 100 mL of solvent as per the concentration 0.5 mg/mL or 500 g/mL ,

So, 250 mg (0.25 g) of serving food need to be added to 100 mL solvent in order to prepare 50 mg of protein/100 mL solution.

Dilution factor = initial amount of protein / final amount of protein

= 6 g / 0.05 g = 120

Hope this helps!
