Hello, I need your help on a calculation...(adsbygoogle = window.adsbygoogle || []).push({});

I have 200 milligram dissolvable tablets, and a 3 ounce dropper bottle of water. How many tablets would I need to add to the water to make a 2% solution?

The chemistry/math is a bit confusing to me because the tables are measured in mass (i.e. mg), whereas water is measured in volume (i.e. oz.).

Thanks in advance for your help
