Question

Which of the following has maximum number of molecules? (A) 2.7 g of NH 3 (B) 1 L SO 2 at STP (C) 2 L of Cl 2 at STP (D) 0.1 mol of H 2 S

Tardigrade Admin · Accepted Answer

Maximum number of moles ⇒ maximum number of molecules NH 3 arrow n =(2.7/17) moles =0.15 moles SO 2 arrow n =(1/22.4) moles =0.04 moles Cl 2 arrow n =(2/22.4) moles =0.08 moles H 2 S arrow n =0.1 moles

Q. Which of the following has maximum number of molecules?

$2.7 g$ of $N H_{3}$

$1 L S O_{2}$ at STP

$2 L$ of $C l_{2}$ at STP

$0.1 m o l$ of $H_{2} S$

Maximum number of moles $\Rightarrow$ maximum number of molecules
$N H_{3} \to n = \frac{2.7}{17}$ moles $= 0.15$ moles
$S O_{2} \to n = \frac{1}{22.4}$ moles $= 0.04$ moles
$C l_{2} \to n = \frac{2}{22.4}$ moles $= 0.08$ moles
$H_{2} S \to n = 0.1$ moles

Q. Which of the following has maximum number of molecules?

2.7g of NH3​

1LSO2​ at STP

2L of Cl2​ at STP

0.1mol of H2​S

Maximum number of moles ⇒ maximum number of molecules NH3​→n=172.7​ moles =0.15 moles SO2​→n=22.41​ moles =0.04 moles Cl2​→n=22.42​ moles =0.08 moles H2​S→n=0.1 moles

$2.7 g$ of $N H_{3}$

$1 L S O_{2}$ at STP

$2 L$ of $C l_{2}$ at STP

$0.1 m o l$ of $H_{2} S$

Maximum number of moles $\Rightarrow$ maximum number of molecules
$N H_{3} \to n = \frac{2.7}{17}$ moles $= 0.15$ moles
$S O_{2} \to n = \frac{1}{22.4}$ moles $= 0.04$ moles
$C l_{2} \to n = \frac{2}{22.4}$ moles $= 0.08$ moles
$H_{2} S \to n = 0.1$ moles
