No. Wine making is both art and science, but using chemicals is the science part of it. So, you need some precision. And we need more information. I assume the tablets are Campden Tablets. As a general rule you add 1 tablet per gallon - 6 gallons, 6 tablets. However, you didn't say what wine you're making, whether you added any k-meta yet and how long you intend to age. All that would help us answer fully.
