In one mole or 18 grams of water, the total negative charge of all the electrons is:
a. zero because its electrically neutral.
b. less than one C
c. almost 100,000 C.
d. almost one million C.
e. none of these

  • physics - ,

    One mole contains 6.02*10^23 molecules.
    Each H2O molecule contains 10 electrons (eight in the O atom and one each in the hydrogen atoms). Each electron has a charge of 1.6*10^-19 C

    Multiply those numbers together for the answer. It's close to a million.
