Question

how much mass would be loss by 1 mole of zinc when it is converted into zinc 2+ion​

Answer 1

ANSWER

CONCEPT USED

$mass \: of \: 1 \: electron \: \\ = \: 1.67 \times {10}^{ - 27 \:} kg$

SOLUTION

reaction

$zn - - - > {zn}^{ + 2} + 2 {e}^{ - 1}$

when one mole of zinc converted into +2 ion then

when one mole of zinc converted into +2 ion then 1 mole of zn lose 2 mole of electron

$mass \: of \: 2 \: mole \: electron = \\ 2 \times 6.022 \times \times 1.67 \times {10}^{ - 27} kg \\ = > 20.11 \times {10}^{ - 4} kg$
