Answer :
The concentration of the stock solution is 11.625m.
The concentration of the stock solution can be calculated using the formula:
concentration of stock solution = (concentration of final solution x volume of final solution) / volume of stock solution
First, let's calculate the concentration of the final solution using the given information:
concentration of final solution = 3m
volume of final solution = 1.55l
Next, we can plug in these values along with the volume of the stock solution (0.4l) into the formula:
concentration of stock solution = (3m x 1.55l) / 0.4l
Simplifying this expression, we get:
concentration of stock solution = 11.625m
Therefore, the concentration of the stock solution is 11.625m.
To find the concentration of the stock solution, we can use the formula that relates the concentration, volume, and amount of solute. By rearranging the formula and substituting the given values, we can solve for the unknown concentration of the stock solution.
