Aballoon contains 11.1 g of nitrogen monoxide gas (no). how many molecules are in the balloon?

The number of molecules that are in balloon are = 2.227 x10^23 molecules

calculation

calculate the number of moles of NO

moles = mass/molar mass

molar mass  of NO = 14+ 16 = 30 g/mol

moles is therefore=  11.1 g/30g/mol= 0.37 moles

by use of Avogadro's constant that is

                                     1 mole= 6.02 x10^23  molecules

                                          0.37 =? molecules

=(6.02 x10^23 x  0.37 moles)/ 1mole=2.227 x10^23 molecules
