Question

A piece of copper contains 6.022 × 10^ 24 atoms.how many mole of copper atom does it contain

Answer 1

Answer:

10∧1 IS THE ANSWER

Explanation:

GIVEN = 6.022 × 10∧24

FORMULA  = NO OF MOLES = NUMBER OF ATOMS / AVOGADRO NUMBER

A.T.Q = NO OF MOLES = 6.022 × 10∧24 / 6.022 × 10∧23 = 10∧1

∴ 10 MOLE IS THE ANS

Answer 2

Given: A piece of copper contains 6.022 × 10^ 24 atoms.

To find: We have to find the number of moles of copper.

Solution:

The symbol of copper is Cu.

Cu is a transition metal of 3d block and has an atomic number 29.

1-mole copper has an atomic weight of 29 u.

1 mole of copper has $6.022×10^{23}$ atoms.

A piece of copper has $6.022×10^{24}$ atoms.

Thus, the number of moles of copper will be-

$\frac{6.022×10^{24}}{6.022 \times {10}^{23} } \\ = 10$

Thus 10 moles of copper.

The piece of copper has 10 moles of copper.
