The total number of electrons present in...

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

A

`6.023xx10^(23)`

B

`6.023xx10^(24)`

C

`6.023xx10^(25)`

D

`6.023xx10^(21)`

Text Solution

Verified by Experts

The correct Answer is:
B
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.
