How many atoms are in 2.5 moles of the compound C3H5(NO3)3 ?
Answer:
a "mole" is an amount. No matter what the size or identity of a substance, there is always 6.022x10^23 "items" in a mole.
A mole of sand has 6.022x10^23 grains (even though thats more than the number of stars in the universe, by far).
2.5 moles of whatever is 2.5 x 6.022x10^23
There are 2.5 x 6.02 x 10^23 molecules in 2.5 moles. However, each molecule has 20 atoms so the answer is 20 x 2.5 x 6.02 x 10^23.
