Question

M(Cu)=32г n(Cu)-? N(Cu)-?

Answer 1

Дано:

m(Cu) = 32 г

Найти:

n(Cu) - ?

N(Cu) - ?

Решение:

n(Cu) = m(Cu)/M(Cu) = 32/64 = 0,5 моль

N(Cu) = n(Cu) * Na = 0,5 * 6,02 * 10^23 = 3,01 * 10^23 молекул

Answer 2

The atomic symbol for copper is Cu, and its atomic mass is approximately 63.55 grams per mole. Therefore:

• The molar mass of copper (M(Cu)) is 63.55 grams per mole.
• Without additional context, it's not possible to determine the number of moles (n(Cu)) or the number of atoms (N(Cu)) of copper. If you provide more information or specify a particular context, I can assist you further.
