.80x+.30y=248
This is equation one.
x+y=400
x=400-y
This is the second equation.
.80(400-y)+.30y=248
320-.80y+.30y=248

To produce 1L of 10% ammonia solution from 25% ammonia solution, you need to dilute the 25% solution by adding a calculated amount of water. To do this, you can calculate the volume of the 25% solution needed and the volume of water needed using the formula: C1V1 = C2V2, where C1 is the initial concentration (25%), V1 is the initial volume, C2 is the final concentration (10%), and V2 is the final volume (1L).
To make a 2% solution from a 25% solution, you need to dilute it. Let x ml be the amount of water needed. Using the equation for mass balance: 0.25(40) = 0.02(40 + x), solve for x to find that x = 875 ml of water needs to be added.
To dilute a 25% glucose and glutamic acid solution, you would mix the solution with an appropriate amount of water. The exact amount of water needed will depend on the desired final concentration of the solution. Calculate the amount of water needed based on the volume and concentration of the original solution.
To make a 1% HCl solution from a 35% HCl solution, you would need to dilute the concentrated solution with water. The ratio of concentrated HCl to water would be approximately 1:34. So, to make 1% HCl, you would mix 1 part of the 35% HCl solution with 34 parts of water.
To prepare the 10% citric acid solution, you will need to dilute the 24% citric acid solution. The amount needed can be calculated using the formula for dilution: C1V1 = C2V2. Given that the final volume is 8 bottles x 3 ounces = 24 ounces and the concentration is 10%, the volume of 24% citric acid needed is (10%)(24 ounces) / 24% = 10 ounces.

To create a 50% chlorinated solution from the 60% and 40% solutions, the chemist will need to mix the two in equal amounts. Therefore, 50 L of the 60% solution and 50 L of the 40% solution are needed to make a 100 L solution that is 50% chlorinated.
To create a 400 L solution that is 62% acid, you would need 200 L of the 80% acid solution and 200 L of the 30% acid solution. This would result in a final solution with the desired concentration.
You need 256 litres.
