The total numebr of electrons present in 18 mL of water density=1gmL^(-1) is

Answer»

`6.02 xx 10^(23)`
`6.02 xx 10^(23)`
`6.02 xx 10^(24)`
`6.02 xx 10^(25)`

Solution :C) 18 mL `H_(2)O` = 18g of `H_(2)O` = 1MOL
`=6.02 xx 10^(23)` molecules
`= 10 xx 6.02 xx 10^(23)` electrons
`6.02 xx 10^(24)` electrons
