Given information
A solution is prepared by dissolving of a mixture of sodium carbonate and sodium bicarbonate in of water. A sample of the solution is then treated with excess and boiled to remove all the dissolved gas. A total of of dry is collected at and .
Step-by-step explanation
Molarity is defined as the number of moles of solute per liter of solution.
The balanced chemical equation for the boiling of the given solution will be,
The balanced chemical equation for the reaction of sodium carbonate with nitric acid will be,
The number of moles of gas are calculated by,
Where,
-
is the number of moles of the gas.
-
is the absolute pressure of the gas.
-
is the volume of the gas.
-
is the absolute temperature of the gas.
-
is the Universal Gas Constant.
Rearranging the equation,
Putting the values in the above equation we get,
