Chemistry Reflection 2

Today, we learned about relative atomic mass and relative molecular mass. Relative molecular mass  is like the sum of atomic mass in a compound so for example H₂O. H₂ is (1x2) while O is 16 so it will be 18 gr/mol. Relative atomic mass is the molecular weight of an atom so it’s the average mass of an atom in an element. So for example Oxygen is 16 while Nitrogen is 14. It’s basically the number in the bottom of the periodic table
