... The molar mass of Cl-35 is 34.968852g and Cl-37 is 36.965903. If 75.77% of chlorine is Cl-35 and 24.23% of chlorine is Cl-37, what is the average molar mass of the chlorine atom in such a mixture? Take the percent average Mass of Cl-35= 75.77% x 34.968852 = 26.4959 Mass of Cl-37= 24.23% x 36.965803 ...
