An unknown solution is prepared by dissolving 50.0g of commercial hydrogen peroxide solution into enough water to make 2.00L of solution. Calculate the percentage of hydrogen peroxide in the commercial product.
PLEASE HELP! I feel like I must be missing a number here or something, because I can't figure this out! Thanks so much!

Yep. You're missing the information that tells you how much H2O2 is in the diluted solution. By the way, the drugstore or grocery store H2O2 is 3%.
Our standard procedure to determine the decomposition rate of hydrogen peroxide includes maintaining a sample for 16 hours at 96°C. A decomposition rate of 5 percent means that after this treatment 5 percent of the original concentration was lost. Thus a 5 percent decomposition of a 50 percent peroxide sample would result in a final concentration of 47.5 percent.
Cleansers do not work. Activity would not subject, neither does weight, height, age, ingesting water or metabolism. How much or little you smoke does not topic either. The physique creates metabolites whilst you smoke (five of them). The test is designed to notice any of them - if only one is reward in any amount, it's a optimistic outcome. The only strategy to clear them is time. It takes 25-30 days.
