Understanding the Problem

To prepare a mouthwash that contains 1:20,000 w/v of Certified Red Dye as a coloring agent, we need to calculate the correct volume of a 1% Stork solution that should be used. This requires a basic understanding of concentration and volume calculations in chemistry.

Defining the Concentration of the Desired Mouthwash

The desired concentration of the mouthwash is 1:20,000 w/v, which means that for every 20,000 grams of the mouthwash, there is 1 gram of Certified Red Dye. To express this concentration in terms of percentage, we can divide the weight of the dye by the total weight of the solution and multiply by 100.

Calculating the Weight of Certified Red Dye Required

To prepare 100 ml of the mouthwash, we need to calculate the weight of Certified Red Dye required. Since the concentration is 1:20,000 w/v, we can calculate the weight of the dye as follows:

Weight of dye = (Concentration x Volume of solution) / 1000 Weight of dye = (1/20,000 x 100) / 1000 Weight of dye = 0.005 g

Calculating the Volume of 1% Stork Solution Required

Since the Stork solution is 1% w/v, we can calculate the volume of the solution required to obtain 0.005 g of Certified Red Dye. We can use the following formula:

Volume of solution = (Weight of dye / Concentration of solution) x 1000 Volume of solution = (0.005 / 0.01) x 1000 Volume of solution = 500 ml

However, this is the volume of the solution required to obtain 0.005 g of Certified Red Dye, not the volume of the 1% Stork solution required to prepare 100 ml of the mouthwash. To calculate the correct volume of the 1% Stork solution, we need to consider the concentration of the dye in the final solution.

Calculating the Correct Volume of 1% Stork Solution

Since the final solution is 1:20,000 w/v, we can calculate the concentration of the dye in the final solution as follows:

Concentration of dye in final solution = (Weight of dye / Volume of final solution) x 1000 Concentration of dye in final solution = (0.005 / 100) x 1000 Concentration of dye in final solution = 0.05%

Since the Stork solution is 1% w/v, we can calculate the volume of the solution required to obtain 0.05% of Certified Red Dye as follows:

Volume of solution = (Concentration of dye in final solution / Concentration of solution) x Volume of final solution Volume of solution = (0.05 / 100) x 100 Volume of solution = 0.05 ml

However, this is the volume of the solution required to obtain 0.05% of Certified Red Dye, not the volume of the 1% Stork solution required to prepare 100 ml of the mouthwash. To calculate the correct volume of the 1% Stork solution, we need to consider the concentration of the dye in the final solution.

Since the Stork solution is 1% w/v, we can calculate the volume of the solution required to obtain 0.05% of Certified Red Dye as follows:

Volume of solution = (Concentration of dye in final solution / Concentration of solution) x Volume of final solution Volume of solution = (0.05 / 100) x 100 Volume of solution = 0.05 ml
