In 1 mole or 18g of water, the total negative charge of all electrons is:
To solve this problem, we must first identify the data we have. we know that there are 10 electrons per molecule of water; At the same time, we know that 1 mole is equal to 6,023x1023 electrons (this thanks to the number of avogadro). So knowing these 2 data, we proceed to multiply them to know the number of electrons that has 1 mole of water,
knowing the amount of electrons in 1 mole of water, we only need to multiply it by 1602x10-19C, since it is the charge of 1 electron. We only have to multiply this value by the amount of electrons in 1 mole of water and we will have the result:
