Some Basic Concepts Of Chemistry Question 330

Question: The number of sodium atoms in 2 moles of sodium ferrocyanide is [BHU 2004]

Options:

A) $ 12\times 10^{23} $

B) $ 26\times 10^{23} $

C) $ 34\times 10^{23} $

D) $ 48\times 10^{23} $

Show Answer

Answer:

Correct Answer: D

Solution:

As we know that four sodium atom are present in sodium ferrocyanide $ [Na _4Fe{{(CN)}_6}] $

Hence, number of $ Na $ atoms = No. of moles $ \times $ number of atom $ \times $ Avogadro?s number $ 2\times 4\times 6.023\times 10^{23}=48\times 10^{23} $
