<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We calculate as follows:
</span>2.0*10^18 molecules of water ( 1 mol / 6.022 x 10^23 molecules ) = 3.32x10^-6 mol water
Because while you use it the electricity gets around and it can burn your hair
if density = m(mass) / v(volume) then the answer would be 3
Answer:
ions with opposite charge
Explanation:
ionic bond is formed between oppositely charged ions in a chemical compound.
An orbital is the most probable location of an electron. This is because you can't pinpoint the exact location of an electron because as soon as you do it will have moved again, so orbitals are used to find the probability of where a certain electron is.
