14) 63 grams of HNO is dissolved in enough water to make 100 liters of solution find percent composition

Answer 1

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%.
