<prompt> Bala boima ba athomo bakeng sa lithium.nan  <response>: Instruction in English: Calculate the atomic mass for lithium. . Response in English: The atomic mass of lithium is 6.941 u. The atomic mass is calculated as the weighted average of the atomic masses of the naturally occurring isotopes of the element, factoring in their relative abundance. For lithium, there are two naturally occurring isotopes: lithium-6 with an atomic mass of 6.015 u and a natural abundance of 7.5, and lithium-7 with an atomic mass of 7.016 u and a natural abundance of 92.5. Using this information, we can calculate the atomic mass of lithium as 0.075 x 6.015 0.925 x 7.016 6.941 u. . Response in Sesotho: Boima ba athomo ea lithium ke 6.941 u. Boima ba athomo bo baloa e le karolelano e lekantsoeng ea boima ba athomo ea li-isotopi tse hlahang ka tlhaho tsa element, ho ipapisitse le bongata ba tsona. Bakeng sa lithium, ho na le li-isotopi tse peli tsa tlhaho: lithium-6 e nang le boima ba athomo ea 6.015 u le bongata ba tlhaho ba 7.5, le lithium-7 e nang le boima ba athomo ea 7.016 u le bongata ba tlhaho ba 92.5. Re sebelisa boitsebiso bona, re ka bala boima ba athomo ea lithium e le 0.075 x 6.015 0.925 x 7.016 6.941 u.
