The initial volume of the gas is 39 L, option C is the correct answer
<h3>What is the combined Gas Law?</h3>According to combined gas law,
PV= nRT
In the Combined Gas Law, if we change either one of the variables the others will also change.
Here , Pressure (P), volume (V), number of mole of gas (n), and temperature (T).
When the moles of the gas is constant , the above equation can be written as ,
The data given in the question is
P = 1.5 atm
V= ? ml
T=325 K
V'= 48 L
P'= 1.2 atm
T' =320 K
Substituting the values in the above formula
Therefore the initial volume of the gas is 39 L, option C is the correct answer
