The volume of 1.2 moles of oxygen gas ( O_2 ) at standard temperature and pressure (STP) is 26.9 Liters

Explanation:

Using ideal gas equation:

PV = nRT

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

At standard conditions of temperature and pressure:

P= pressure = 1 atm

T = temperature = 273 K

V= volume = ?

Given: n = no of moles = 1.2

R= gas constant =0.0821 Latm\molK

Putting in the values we get:

$V=\frac{1.2\times 0.0821Latm/Kmol\times 273}{1atm}=26.9L$

The volume of 1.2 moles of oxygen gas ( O_2 ) at standard temperature and pressure (STP) is 26.9 Liters
