Sagot :

Answer:

5.96 * 10^23 molecules

Explanation:

Don't start counting up the number of CsHsNs and Os there are Counting up the atom ions will get a wrong answer.  The question is asking for the number of molecules. That means you do not break down each molecule to  find the number of molecules. You modify 1 mol to find out how many molecules are in 0.99 mols. Do that using a proportion.

1 mol contains 6.01 * 10^23 molecules

0.99 mol contains x

1/0.99 = 6.02 * 10^23 / x molecules

x = 0.99 * 6.02 * 10^23

x = 5.96 * 10^23
