Question

One mole of $P_4$ molecules contains:

• A. 1 molecule of P
• B. 4 molecules of P
• C. 236.022 $\times$ ${10}^{41}$ atoms of P
• D. 24.088 $\times$ ${10}^{23}$ atoms of P
  

Answer 1

The correct option is D

24.088 $\times$ ${10}^{23}$ atoms of P

1 mole of P contains $6.022\times {10}^{23}$ particles
Hence 4 P moles contain $4\times 6.022\times {10}^{23}=24.088\times {10}^{23}$ particles
