Question

A piece of Cu contains $6.022\times {10}^{24}$ atoms. How many mole of Cu atoms does it contain?

• A. 10 mole
• B. 5 mole
• C. 2 mole
  
• D. 1 mole
  

Answer 1

The correct option is A 10 mole

1 mole = $6.022\times {10}^{23}$. Hence $6.022\times {10}^{24}$ will contain = $\frac{6.022\times {10}^{24}}{6.022\times {10}^{23}}=10$ moles.
