14) 63 grams of HNO is dissolved in enough water to make 100 liters of solution find percent composition
To find the percent composition of the solution, we need to calculate the total mass of the solution first.
The molar mass of HNO3 is approximately 63 grams/mol.
To find the number of moles of HNO3 in the solution, we can use the formula:
moles = mass / molar mass
moles = 63 grams / 63 grams/mol = 1 mol
Since there is 1 mole of HNO3 in the solution, the total mass of the solution will be:
mass of solution = mass of solute + mass of solvent
mass of solution = 63 grams + (100 liters x 1000 grams/liter) = 63 grams + 100,000 grams = 100,063 grams
Now, we can calculate the percent composition of HNO3 in the solution:
percent composition = (mass of HNO3 / mass of solution) x 100
percent composition = (63 grams / 100,063 grams) x 100
percent composition ≈ 0.063%
Therefore, the percent composition of HNO3 in the solution is approximately 0.063%.
