Please help me in my chem question Madam @Preetha

preetha · Answer

That is a big task. A mole is a unit of measurement.  Like dozen.  A dozen is 12 things.  Dozen eggs = 12 eggs. A mole is 6.023 x 10 23 things.  Mole of ions = that many ions.  But a mole of C has a mass = 12 g.  A mole of H atoms has a mass = 1 g.  A mole of H2O has a mass = (2+16) = 18 g.  Read your book and come back with questions.
