Question

What is the volume of 3.2 moles of chlorine gas (Cl2) at standard temperature and pressure (STP)?. . 7.0 L. . 14 L. . 22. L. . 72 L

Answer 1

Answer : The volume of 3.2 moles of chlorine gas
`(Cl_2)` at standard temperature and pressure (STP) is, 72 L

Solution : Given,

Moles of chlorine gas
`(Cl_2)` = 3.2 moles

As we know that, at standard temperature and pressure (STP)

1 mole of chlorine gas contains 22.4 L volume of gas

So, 3.2 moles of chlorine gas contains
`22.4* 3.2=71.68=72L` volume of gas

Therefore, the volume of 3.2 moles of chlorine gas
`(Cl_2)` at standard temperature and pressure (STP) is, 72 L

Answer 2

There are numerous information's already given in the question. The answer can be easily deduced using those given information's.

Amount of chlorine gas = 3.2
1 mole of gas at STP = 22.4 liters
Then
Volume of chlorine gas = 3.2 * 22.4
= 72 liter.
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the fourth option or the last option.
