To determine the value of the total charge of electrons in 1 g of water, we apply the formula: q = N * qe = n * (m / M) * Na * qe.

Constants and variables: n – the number of electrons in 1 water molecule (n = 10 electrons); m is the mass of water (m = 1 g); M – molar mass (M = 18 g / mol); Na – Avogadro’s number (Na = 6.02 * 10 ^ 23 mol-1); qе – electron charge (qе = -1.6 * 10 ^ -19 C).

Calculation: q = n * (m / M) * Na * qe = 10 * (1/18) * 6.02 * 10 ^ 23 * (-1.6 * 10 ^ -19) = -5.35 * 10 ^ 4 Cl = -53.5 kC.

Answer: The total charge is -53.5 kC.
