Web28 feb. 2024 · Lithium-7 is the second stable lithium isotope and the most abundant. Li-7 accounts for about 92.5 percent of natural lithium. Because of lithium's nuclear properties, it is less abundant in the universe than helium, beryllium, carbon, nitrogen, or oxygen. Lithium-7 is used in the molten lithium fluoride of molten salt reactors. WebLithium has two naturally occurring isotopes: 6 (Li) Lithium has a mass of 6.015 and is 7.42% abundant; 7 (Li) Lithium has a mass of 7.016 and is 92.58% abundant. Calculate the atomic mass of lithium. 6.015 multiplied by 0.0742 + 7.016 multiplied by 0.9258 = 6.94

WebThe mass of lithium-6 is 6.01512 amu and the mass of lithium-7 is 7.01601 amu. Calculate the relative abundances of the two isotopes. Show Answer. Verified Solution. This video solution was recommended by our tutors as helpful for the problem above. 1993 views. 1. Was this helpful? 1. Previous problem. WebFirst, we define one. of the abundances as x. In this case, the abundance of 6 Li will be x. This means that the abundance of 7 Li= 1-x. Using what we learned above, we can set up an equation. 6 amu (x) + 7 amu (1-x)= 6.94 amu There is only one variable, so we can easily solve for x. 6x + 7 – 7x= 6.94 6x-7x= -0.06 -x = -0.06 x= 0.06 how come you 意味
