Question

Assertion : 1 mole of H 2 and O 2 each occupy 22.4 L at standard temperature and
pressure.
Reason : Molar volume for all gases at the standard temperature and
pressure has the same value.

a) Both A and R are true, and R is correct explanation of the assertion.
b) Both A and R are true, but R is not the correct explanation of the assertion.
c) A is true, but R is false.
d) A is false, but R is true.

Answer 1

Answer:

A BUT NOT SURE IF ITS CORRECT FOLLOW ME BACK

Answer 2

Answer:

Both A and R are true, and R is the correct explanation of the assertion. i.e.(a).

Explanation:

This question is based on the concept of Avogadro's law.

• Avogadro's law, also known as Avogadro's principle or Avogadro's hypothesis, is a gas law that asserts that, given constant temperature and pressure, the volume occupied by a gas is directly proportional to the number of atoms or molecules that make up that gas (i.e., the amount of gaseous substance).
• Avogadro's law connects temperature, pressure, volume, and substance amount for a certain gas, which makes it closely related to the ideal gas equation.

$\mathrm{V\propto n }$           (1)

Where,

V=volume occupied by the gas

n=number of moles of the gas

So, the correct answer among the given options is (a) i.e.Both A and R are true, and R is the correct explanation of the assertion.
