Boron (B; Z = 5) has two naturally occurring isotopes. Find the percent abundances of 10B and 11B given these data: atomic mass of B = 10.81 amu, isotopic mass of 10B = 10.0129 amu, and isotopic mass of 11B = 11.0093 amu. (Hint: The sum of the fractional abundances is 1. If x = abundance of 10B, then 1 −x = abundance of 11B.)
- 25. The average atomic masses of some elements may vary, depending upon the sources of their ores. Naturally occurring boron consists of two isotopes with accurately known masses (10B, 10.0129 amu and 11B, 11.00931 amu). The actual atomic mass of boron can vary from 10.807 to 10.819, depending on whether the mineral source is from Turkey or the United States. Calculate the percent abundances leading to the two values of the average atomic masses of boron from these two countries.10. Platinum has six isotopes: 190Pt, 192Pt, 194Pt, 195Pt, 196Pt, and 198Pt. The natural abundances of the six isotopes are 0.014% ¹⁹⁰Pt (189.96 amu); 0.782% ¹⁹²Pt (191.96 amu); 32.967% ¹⁹4Pt (193.96 amu); 33.832% ¹95Pt (194.97 amu); 25.242% ¹9Pt (195.97 amu); and 7.163% ¹98Pt (197.97 amu).
