KATRIN_1 [288]

Answer:

3

Explanation:

The law of conservation of energy states that energy cannot just be created, so answer one is out. Energy also cannot be simply destroyed, so answer to is out as well. From here it gets tricky, since both answers make some sense under these rules. However, absorbed is bassically the same as destroying it leaving only answer three. Answer three <em>does</em> obey these laws, as energy can be converted.

Lithium forms compounds which are used in dry cells and storage batteries and in high-temperature lubricants. It has two natural
agasfer [191]

The naturally occurring isotopes of Li are Li-6 of mass 6.015121 amu and Li-7 of mass 7.016003 amu. The atomic mass of Li is 6.9409 amu, the percent abundance can be calculated using the following relation.

Atomic mass=m(Li-6 )×%(Li-6 )+m(Li-7 )×%(Li-7 )

Let the percent abundance of Li-6 be X thus, that of Li-7 will be 1-X, putting the values,

6.9409 amu=6.015121 amu\times X+7.016003 amu(1-X)

Or,

6.9409 =6.015121 X+7.016003-7.016003 X

Or,

X=0.075

Thus, 1-X=1-0.075=0.925

Thus, percent abundance of Li-6 is 0.075 or 7.5 % and that of Li-7 is 0.925 or 92.5%.
