Calculate the mass percent, % (m/m), for the solute in each of the following solutions.
7.0 g of CaCl in 65.0 g of Ca Cl solution
To calculate the mass percent, % (m/m), we need to divide the mass of the solute by the mass of the solution, and then multiply by 100.
The mass of the solute is 7.0 g.
The mass of the solution is 65.0 g.
Mass percent = (mass of solute / mass of solution) x 100
Mass percent = (7.0 g / 65.0 g) x 100 = 10.77%
Therefore, the mass percent of the solute in the solution is 10.77%.
To calculate the mass percent (% m/m) of the solute (CaCl2) in the solution, you need to determine the mass of CaCl2 and divide it by the mass of the entire solution, then multiply by 100.
Given:
Mass of CaCl2 (solute) = 7.0 g
Mass of CaCl solution = 65.0 g
Step 1: Calculate the mass percent (% m/m) of the solute.
Mass of CaCl2 = 7.0 g
Total mass of solution = 65.0 g
Mass percent (% m/m) = (mass of solute / mass of solution) * 100
% m/m = (7.0 g / 65.0 g) * 100
% m/m = 0.1077 * 100
% m/m ≈ 10.8%
The mass percent (% m/m) of the solute (CaCl2) in the solution is approximately 10.8%.
To calculate the mass percent, we need to know the mass of the solute and the mass of the solution. The mass percent is the ratio of the mass of the solute to the mass of the solution, multiplied by 100%.
In this case, the mass of the solute is given as 7.0 g of CaCl. The mass of the solution is given as 65.0 g of Ca Cl solution.
To find the mass percent, we can use the following formula:
Mass percent = (mass of solute / mass of solution) x 100%
Substituting the given values into the formula:
Mass percent = (7.0 g / 65.0 g) x 100%
Now we can calculate the mass percent:
Mass percent = 0.1077 x 100%
Mass percent = 10.77%
Therefore, the mass percent of the solute in the given solution is 10.77%.
