Answer 1

hey friend☺☺☺
here is ur ans
After you have found the number of moles of methane (CH4), you should multiply this number by avogadro number (6.022 * 10^23) and you get the number of molecules. Here is the calculation: n = 8.0 gr / 16.043 gr/mol = 0.499 mol. Number of molecules =0.499 mol * (6.022 * 10^23 1/mol) = 3.005 * 10^23 molecules.
