The total number of electrons present in 18mL. Water(density 1g/mL) is:

Answer»

`6.023xx10^(23)`
`6.023xx10^(24)`
`6.023xx10^(25)`
`6.023xx10^(21)`

Solution :MASS =18g
NUMBER of molecules of `H_(2)O` in 18g mass `=6.023xx10^(25)`
Number of electrons in 18g water `=6.023xx10^(@3)xx10`
`=6.023xx10^(24)`
`because ` Each MOLECULE of water contains 10 electrons.
