Answer» archWhat WOULD you like to ask?CHEMISTRYavatarAsked on DECEMBER 26, 2019 byRammy SalmaThe isotopic abundance of C-12 and C-14 is 98% and 2% respectively. What would be the NUMBER of C - 14 isotope in 12 g CARBON sample? ShareStudy laterANSWERIsotopic abundance of C−12 is 98%Isotopic abundance of C−14 is 2%Average atomic mass = 100Mass number×Relative abundance + Mass number×Abundance = 10098×12+2×14 =12.04 gramsSo, in 100 grams of carbon sample, C−14 isotope will be 2 grams since it is 2% in abundance.∴ in 12 grams sample, C−14 isotope will be = 10012×2 =0.24 grams1 mole of any compound has N A number of atoms i.e 6.02×10 23 . So, C−14 isotope will be 1.032×10 22Hope this will help you.
