230 kg....water

370 kg....(water soluble) chemical solution

During making the first mixture he made a mistake,he put:

230 kg water

470 kg chemical solution :duh:

How can he correct this mistake? without losing any material.

These mixtures are normally mixed in 750 Liter containers.

I hate when I do that.

Divide the solution in half. Add 135kg of chem and 115kg of water to each container.

Original solution was 600kg of 61 2/3% chemical. Mistake was 700kg 67 1/7% chemical. When you divide it, you have 350kg of 67 1/7% chemical - or 235 kg of chemical and 115kg of water. Then just make up the difference to get you back to the required amount.

:unsure:

I got 105 for water, 145 for chemical. - I divided the solution made then added enogh water (14.5) to each to fix current mixture, then added 146.01 - chemical and 89.49 - water to bring the amount to 600. Where did I go wrong?

pour half the content into second container...

Now, each container has 115 lt water and 235 lt solution.

So, you need to add 115 lt water and 135 lt solution in each container.

EDIT: spell-check
