Answer:
The mass is
Explanation:
From the question we are told that
The volume of oxygen produced is
The temperature is
The pressure is
From the ideal gas law we have that
Where R is the gas constant with the value
n is the number of moles making it the subject of the formula
Substituting values
From the chemical equation
one mole of produces one mole of kCl and
of oxygen
x mole of produces x mole of kCl and
of oxygen
So
Now the molar mass of KCl is a constant with a value
Now the mass of KCl is mathematically evaluated as
Substituting values
