You are supplied a flask of 1.5 ltr capacity, Now a particularly gas is filled inside the flask at normal atmospheric pressure. IF The pressure becomes half of the normal atmospheric pressure, what quantity of gas will be evacuated from the flask ?

Explanation:
Ideal gas law equation:-
The properties of an ideal gas are all summarized in one formula of the form:
pV = nRT
where:
p is the pressure of the gas, measured in Pa;
V is the volume of the gas, measured in m³;
n is the amount of substance, measured in moles;
R is the ideal gas constant; and
T is the temperature of the gas, measured in Kelvins.
To find any of these values, simply enter the other ones into the ideal gas law calculator.
For example, if you want to calculate the volume of 40 moles of a gas under a pressure of 1013 hPa and at a temperature of 250 K, the result will be equal to:
V = nRT/p = 40 * 8.3144598 * 250 / 101300 = 0.82 m³.
Ideal gas constant:-
The gas constant (symbol R) is also called the molar or universal constant. It is used in many fundamental equations, such as the ideal gas law.
The value of this constant is 8.3144626 J/(mol·K).
The gas constant is often defined as the product of Boltzmann's constant k (which relates the kinetic energy and temperature of a gas) and Avogadro number (the number of atoms in a mole of substance):
R = NAk = (6.02214076 × 1023 /mol) * (1.38064852 × 10-23 J/K) = 8.3144626 J/(mol·K)
