Answer: 0.714 moles of
will be produced from 237.1 g of potassium iodide
Explanation:
To calculate the moles :

The balanced chemical reaction is:
According to stoichiometry :
2 moles of
produce = 1 mole of 
Thus moles of
will require=
of 
Thus 0.714 moles of
will be produced from 237.1 g of potassium iodide
Ans: Ce
Cerium is a chemical element with the symbol Ce and atomic number 58.
We should indicate first and foremost the assumption of ideal gas behavior so that we can use the ideal gas equation written below:
PV = nRT
For this problem,let's solve for V. Rearranging the equation,
V = nRT/P
Substituting the values,
V = (1 mol)(0.0821 L-atm/mol-K)(30 + 273 K)/1.2 atm
<em>V = 20.73 L of N₂ gas</em>
