You are given 500ml of a solution at pH 7.0 containing an unknown concentration of ATP (for which E- the molar coefficient= 14,300M^-1 cm^-1 at 260nm and pH 7.0). You place 4mL of this solution in a 1cm wide, 1cm long, 4cm high cuvette and determine the A260 to be 0.143. What is the molarity of the ATP solution? How many moles of ATP are in the 500mL of solution? How many μ moles of ATP are in your curvette?
