Question

How many molecules are present in each sample? 2.50 mol SO, molecules so, 0.483 mol CO: molecules CO molecules NH, a sample of NH, containing Avogadro's number of molecules:

Answer 1

To find the molecules Given that 2.50m ol of So, Avogadro's constant says that Imole of any atom contains 6.022x102s molecules 1 mole = 6.022x10 molecules 2.50m ol of So, = 2.50x6.022x10% molecules = 1.50x1024 molecules Hence the molecules of 2.50mol of SO, = 1.50x1024 molecules (b) To find the molecules Given that 0.483 mol CO Avogadro's constant says that Imole of any atom contains 6.022x10" molecules 1 mole = 6.022x10molecules So 0.483 mol CO=0.483x6.022x10molecules = 2.90x102 molecules Hence the molecules of 0.483mol CO= 2.90x10molecules Asample of NH containing Avogadro's number of molecules = 6.022x10"molecules
