v/v % = [ (volume of solute)/ (volume of solution)] x 100%. Note that volume percent is relative to the volume of solution, not the volume of solvent. For example, wine is about 12% v/v ethanol. This means there is 12 ml ethanol for every 100 ml of wine. It is important to realize liquid and gas volumes are not necessarily additive.
16.9 oz bottles are something of an international standard. The size in metric is 500 mL or 0.5 L. So this size bottle arises from the same standards as 2 liter bottles and 1 liter bottles, but for some reason instead of calling them half liters, people resort to calling them 16.9 oz. Is 8 bottles of water a day too much?
To determine how many cups are in 500ml, divide the amount of milliliters by 236.59. The result is equivalent to 2.11 cups, or just over two cups. As a reminder, 1 cup is equal to 236.59 milliliters (ml). This means that if you need 500ml of liquid for a recipe, you can use 2.11 cups to get the desired amount.
500 Milliliters (mL) = 0.5 Liters (L) Visit 500 Liters to Milliliters Conversion Milliliters : A milliliter (also written "milliliter"; SI symbol ml) is a non-SI metric system unit of volume which is commonly used as liquid unit. It is equal to 1/1000 liter, or one cubic centimeter, therefore, 1ml =1/1000 L =1 CM3.
1 litre = 1000ml (millilitres)so 500ml =0.5ltrOther way roundTwo2 x 500 ml = 1,000 ml = 1 litre. . 499 492 446 250 144 166 333 270
