If 8.87 g of CuNO3 is dissolved in water to make a 0.500 M solution, what is the volume of the solution?
Are you sure of that formula?
mols = 8.87/molar mass = ?
Then M = mols/L. YOu know mols and M, solve for mL.
To find the volume of the solution, we need to use the formula for molarity:
Molarity (M) = moles of solute / volume of solution (in liters)
In this case, we are given the molarity (0.500 M) and the mass of the solute (8.87 g of CuNO3). To find the number of moles of CuNO3, we need to know its molar mass.
The molar mass of CuNO3 can be calculated by adding up the atomic masses of copper (Cu), nitrogen (N), and three oxygen (O) atoms.
CuNO3: Cu (63.55 g/mol) + N (14.01 g/mol) + (O x 3) (16.00 g/mol) = 79.55 g/mol
Now, we can calculate the number of moles of CuNO3:
moles = mass / molar mass = 8.87 g / 79.55 g/mol
moles ≈ 0.1115 mol
Now, we can rearrange the molarity formula to solve for the volume of the solution:
Volume of solution = moles of solute / Molarity
Volume of solution = 0.1115 mol / 0.500 M
Volume of solution ≈ 0.223 L
Therefore, the volume of the solution is approximately 0.223 liters.
