A student makes a solution by measuring out 100 grams of solute and dissolving it in lots of water. The student then measures the mass of the resulting solution. He converts the mass of the solute into moles and divides that by the mass (in kg) of the solution. He reports the result as the molality of the solution. Why is the student wrong

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
