1.	A solutioncontains 1 milli-curiefo L- phenyol alanine C^(14)(unifromly labellled) in 2.0mL solution. The activity of labelled sample is given as 150 milli-curie/milli-mole. Calculatate: (a) The concentration of sample in the solution inmol/litre. (b) The actitivity of the solution in terms of counting per minute/mL at a countingefficiencyof 80%.
