Question

12.044 ×1023 number of he atoms ( finding mole from number)​

Answer 1

Answer:

2 moles

Thus there are 2 moles of He atom in 12.044 X 1023 atoms of He ( helium )

Explanation:

One mole of any element contains 6.022 X 1023 atoms of the element. Thus 1 mole of He atom consists of 6.022 X 1023 atoms of He. Thus

6.022 X 1023 atoms of He = 1 mole of He atom

1 atom of He=1/(6.022 X 1023) moles of He

So 12.044 X 1023 atoms of He = (1X 12.044 X 1023)/(6.022 X 1023) moles of He

= 2 moles of He atom

Thus there are 2 moles of He atom in 12.044 X 1023 atoms of He ( helium )
