Let us consider 1 cup = 250 mL = 250g
We know Density of Water =
(or)
where g=grams, cc= centimeter cube, mL= mili litre
We know the formula of water is
Therefore in 18g of
there are 8 protons and 8 electrons.
=> The number of protons and electrons each in 250 g of water are
=> There are 111 protons and 111 electrons in 250 mL of water
We know charge of 1 electron =
and
charge of 1 proton =
Therefore
positive charge in a cup of water =
and
positive charge in cup of water =
