##### Connection between Avogadro’s number and molar mass
« on: September 28, 2020, 07:27:21 PM »
I don’t understand the connection between Avogadro’s number and molar mass. I know that 1 mole is 6.022 x 10^23 particles, but 1 mole is also the atomic mass of 1 atom? I just don’t understand the point of Avogadro’s number if we can just use atomic and molar mass instead.

The first statement  1 mole is 6,023 * 1023  particles is correct.
But the statement 1 mole is the molar mass of one atom is wrong.
According the first statement the molar mass is the mass of  6,023 *1023  atoms.
