You're an industrial chemist working for a pulp and paper industry manufacturer. A big part of your job involves making sure a chemical process will be as effective in the manufacturing process as it was when you discovered it in the lab.

Today you're testing the effects of different levels of hydrochloric acids in a water solution used to treat wood products and prepare them for processing. The solution is applied to the wood products like a shower, and comes from a vat through a pipe at about 100 liters per minute for 5 minutes. After the 5 minutes are up, the shower shuts off and the wood products simply soak in the solution.

Your lab tests have shown a solution of 8 percent hydrochloric acid (by weight) is the most effective strength for this type of treatment. Now you need to figure out what this means on the manufacturing floor, so you can provide some directions for your company's industrial chemical workers.

Using past records about this treatment system, you discover the density (weight) of the whole solution is 0.85 kilograms per liter. How many kilograms of hydrochloric acid need to be used in this solution?
