Question

मोलर आयतन का मात्रक क्या होता है

​

Answer 1

Answer:

समान ताप एवं दाब पर किसी गैस के एक मोल का आयतन 22.4L या 22400 ML होती है, जिसे मोलर आयतन कहते हैं।

Answer 2

The unit of molar volume is, liter/mol (L/mol)

Explanation:

Molar volume : It is defined as the 1 mole of a gas occupies 22.4 L volume at standard temperature and pressure.

Using ideal gas equation:

PV = nRT

$V=\frac{nRT}{P}$

where,

V = molar volume

n = number of moles = 1 mole

R = gas constant = 0.0821 L.atm/mol.K

T = temperature = 273 K

P = pressure = 1 atm

Now put all the given values in the above formula, we get:

$V=\frac{1mol\times 0.0821 L.atm/mol.K\times 273K}{1atm}$

$V=22.4L$

The molar volume of gas at standard temperature and pressure is, 22.4 L/mol

Hence, the unit of molar volume is, liter/mol (L/mol)
