Question

No. of electrons in 1.8 ml of $H_{2}O$(l) is

• A. 6.02 x 10²³
• B. 3.011 x 10²³
• C. 0.6022 x 10²³
• D. 60.22 x 10²³

Answer 1

The correct option is A

6.02 x 10²³

$n\left(H_{2}O\right)$ = $\frac{1.8}{1.8}$ =0.1

1molecule of $H_{2}O$ contains 10 $e^{-}$s

18g=1mole of $H_{2}O$ contains 10 mole $e^{-}$s

1.8g=0.1mole of $H_{2}O$ contains 1 mole $e^{-}$s
