How many molecules of H2O are in 8.54 moles of H2O? Select one:
a)5.14 * 10^24 molecules H2O
b)2.86 * 10^23 molecules H2O
c)6.02 * 10^23 molecules H2O
d)5.14 * 10^23 molecules H2O

a)5.14 * 10^24 molecules H2O

Explanation:

8.54 moles of H2O contains 8.54 x 6.022 x 10^23 = 5.14 x 10^24 molecules of H2O.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
