The concentration of commercially available concentrated nitric acid is 70% , or 15.9M
In 100 grams of solution there are 1.11 mol of HNO3.
Calculate the volume of 100 g of the Solution.
To calculate the volume of 100 grams of the solution, we need to know the density of the solution. Unfortunately, the given information does not include the density. However, we can still make an approximation using the molar mass of concentrated nitric acid and the given concentration.
Step 1: Find the molar mass of HNO3:
H = 1.01 g/mol
N = 14.01 g/mol
O = 16.00 g/mol
Molar mass of HNO3 = (1.01 * 1) + (14.01 * 1) + (16.00 * 3) = 63.01 g/mol
Step 2: Calculate the moles of HNO3 in 100 grams of the solution:
Given moles of HNO3 = 1.11 mol
Step 3: Use the molar mass to convert moles to grams:
Grams of HNO3 = moles of HNO3 * molar mass of HNO3
Grams of HNO3 = 1.11 mol * 63.01 g/mol = 69.94 g
Step 4: Calculate the grams of water in the solution:
Grams of water = total grams of solution - grams of HNO3
Grams of water = 100 g - 69.94 g = 30.06 g
Step 5: Calculate the volume of water using the density of water:
Density of water = 1 g/mL
Volume of water = grams of water / density of water
Volume of water = 30.06 g / 1 g/mL = 30.06 mL
Therefore, the volume of 100 grams of the solution is approximately 30.06 mL.
