85. Solving a chemistry problem

33. A pure glycine containing a radioactive isotope 14 C with a specific activity of 25,000 pulses per minute • g was added to a sample of hydrolyzed protein. The glycine isolated from the mixture shows the specific activity Ax. Calculate the content of glycine (g) in the hydrolyzed protein from the following data:

sample 1 2 3 4 5
a, d 0.1000 0.2000 0.3000 0.4000 0.5000
Ah, imp/min•g 442 840 1240 1625 2000
