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} $
