Masa molowa miedzi wynosi 63,54 g/mol. Oblicz masę jednego atomu miedzi.
M (masa molowa) Cu= 63,54g/mol
NA - liczba Avogadra = 6,022 * 10²³ 1/mol
m(masa atomu) Cu = M : NA = 63,54 g/mol : 6,022* 10²³ 1/mol
= 1,06*10⁻²²g Cu
m miedzi =63,54g/mol
63,54 : 6,02 x 10 do potęgi minus 23 to 10,54 x 10 do potęgi minus 23 [gram]
