The total number of electrons present in `18 mL` of water is ……

A

`6.022xx10^(23)`

B

`6.022xx10^(24)`

C

`6.022xx10^(25)`

D

`6.022xx10^(21)`

Text Solution

Verified by Experts

The correct Answer is:
B
Mass = 18 g
Number of molecules of `H_(2)O` in 18 g mass
`= 6.022 xx 10^(23)`
Number of electrons in 18 g water
`= 6.022 xx 10^(23) xx 10 = 6.022 xx 10^(24)`
( `:.` Each molecule of water contains 10 electrons.)
