Web14 mrt. 2024 · To answer this, first calculate how many electrons are in 1 kg of water, then multiply that by the charge per electron (1.602 x 10^-19 coulombs). The molecular weight of water is 18, so there are 1000 / 18 = 55.55 moles of water in 1 kg. Multiply that by Avogadro's number (6.02 x 10^23) to get the number of water molecules WebThis allows us to cancel the units of moles of hydrogen. Finally, we can convert to grams of water by multiplying by water’s molar mass, which is 18 grams per mole. In this step, the units of moles of water are canceled. Now we’re ready to calculate the grams of water produced. Let’s start with 0.5846 grams and divide by two.
