Depends on the density of the liquid. Mercury, for example, is around 13 times as dense as water and so the mass of 16 liq oz of mercury will be 13 times that of water.

Assuming you mean dry ounces, not the liquid measure, there are 30 (actually 28.35 and change) grams in one ounce. So 13 ounces is about 390 grams, or 368 if you want to be very precise.

If this is for a recipe, then this should helpyou: 200 milliliters equals 7/8 cups. Since there are 8 ounces in one cup, and 16 tablespoons in one cup, you can use 13 1/2 tablespoons, or one cup minus 2 1/2 tablespoons. This will give you 199.6 milliliters.

One tablespoon of sugar is 13 grams approximately. We can know the number of tablespoons by dividing 10 by 13. In this case the answer is 0.77 tablespoons.
