Authoritative PPT Summary
"Quantities represented by element symbols" PPT courseware
Part One: Relative Atomic Mass
International regulations: relative atomic mass is used to express the mass relationship of atoms.
Taking 1/12 of the atomic mass of carbon-12 as a standard, the value obtained by comparing the masses of other atoms with it is the relative atomic mass of the atom.
Can it be represented by a formula?
relative atomic mass of an atom
=actual mass of an atom/atomic mass of C-12×1/12
=Mass of a certain atom×12/Atomic mass of C-12
1. If the mass of C-12 is a and the mass of A atom is b, then the relative mass of A atom is _______
2. It is known that the relative mass of A atom is 16, and 1/12 of the mass of C-12 is 1.661×10-27 kg. Find the mass of A atom.
3. It is known that the relative atomic masses of iron and carbon are 56 and 12 respectively. Do iron and carbon with the same mass contain the same number of atoms? Please explain why.
Quantity represented by element symbol PPT, part 2 content: relative molecular mass
The sum of the relative atomic masses of the atoms in a molecule is the relative molecular mass of the molecule
Find the relative molecular mass of carbon dioxide
step:
1. Write the correct chemical formula
2. Find out the relative atomic mass of each element
3. Relative molecular mass = the sum of the relative atomic masses of each atom
