What is the total charge of all the electrons in 1.0L of liquid water?

Answer 1

density of water is 1g/cm³

1 cm³ = 1ml

1 liter has 1000mL then 1 L of water mass to 1 kg.

each water molecule has 10 eletrons and each mole of water has a mass of 18 grams.

so 1 liter of water contains 1000 / 18 = 55.6 moles.

1 mole = 6.02 * 10 ^23 of those object then water has a total of = 55.6 * 6.02 * 10^23 = 3.35 * 10^25 water molecules.

each water molecule has 10 eletrons = 3.35 * 10^25 * 10

= 3.35 * 10^26 eletrons in 1 L of water

each eletron has a charge of - 1.602 * 10 ^ - 19 C

thus all the electrons together gives a charge of

= 3.35 * 10^26 × - 1.602 * 10^-19

= - 5.36 * 10^7 C

this is the most accurate answer so check your given answer again.
