A quart is 32 ounces. The usual "bleach" is a 1.25% bleach solution, so you can't easily make a 5% solution from it. If you had pure "bleach" (usually sodium hypochlorite), you would need 5% of 32 ounces, which is 1.6 ounces of it. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
