percent composition 63 grams of HNO, is dissolved in enough water to make 100 liters of solution
To calculate the percent composition of a solution, we need to know the total mass of the solution and the mass of the solute.
The molar mass of HNO3 is 63 grams/mol.
First, let's calculate the moles of HNO3 in 63 grams:
63 grams / 63 grams/mol = 1 mol
Next, let's calculate the molarity of the solution:
Molarity = moles of solute / volume of solution in liters
Molarity = 1 mol / 100 L = 0.01 mol/L
Now, we can calculate the percent composition of HNO3 in the solution:
Percent composition = (moles of solute / moles of solution) * 100
Percent composition = (1 mol / (100 L * 0.01 mol/L)) * 100
Percent composition = 1%
Therefore, the percent composition of the HNO3 solution is 1%.
