Isotope Abundance

The nuclear power industry extracts 6^6Li but not 7^7Li from natural samples of lithium. As a result, the average molar mass of commercial samples of lithium is increased. The current abundace of the two isotopes are 7.42% and 95.58% respectively, and the masses of their atoms are 9.968 x 1024^{-24} g and 1.165 x 1023^{-23} g. What is the current molar mass of a natural sample of lithium?
