Platinum has six isotopes: 190Pt, 192Pt, 194Pt, 195Pt, 196Pt, and 198Pt. How many neutrons are there in each isotope? The natural abundances of the six isotopes are 0.014% 190Pt (189.96 u); 0.782% 192Pt (191.96 u); 32.967% 194Pt (193.96 u); 33.832% 195Pt (194.97 u); 25.242% 196Pt (195.97 u); and 7.163% 198Pt (197.97 u).Calculate the average atomic mass of platinum and compare it with the value in the periodic table on the inside front cover.
