What is the number of moles of Cl atoms present in n moles of tear gas and in n moles of mustard gas respectively?

Options

A $2n$ and $3n$
B $3n$ and $2n$
C $n$ and $3n$
D $n$ and $2n$

Correct answer

B. $3n$ and $2n$

Step-by-step solution

The chemical formula of tear gas (chloropicrin) is

CCl_3NO_2

.

One molecule of tear gas contains

3

chlorine atoms. Therefore,

n

moles of tear gas contain

3n

moles of Cl atoms.

The chemical formula of mustard gas is

S(CH_2CH_2Cl)_2

.

One molecule of mustard gas contains

2

chlorine atoms. Therefore,

n

moles of mustard gas contain

2n

moles of Cl atoms.

Answer:

3n

and

2n
