How much of a gallon of milk is water?
It Goes Like This>kida hard to explain< Milk Is Taken From The Dairy Farm To The Milk Company. No Water Is Added. It Goes Through All The Filterlng, Pasturising, Ect. Then It Is Ran Into A Filter That Removes The Butterfat. Then If You Get 2% Milk They Add Back Into The Milk 2% Of The Butterfat It Would Have Had. In Whole Mil;k They Add All The Butterfat That Is Natural To The Milk. Skim Has No Butterfat Added. The Only Water That Is There Is What Mother Nature Added. But You Know There Is Water There. How Much, I Don`t Know. I Hope This Helped
Whole milk is generally about 87% water. The rest of it is made up of milkfat and NMS, or Non-fat Milk Solids (proteins, lactose, etc).
The weight of a gallon of milk is only slightly greater than a gallon of water, about 3% more. A US gallon with 2% milkfat weighs about 8.4 pounds, compared to 8.6 pounds for "whole milk" and 8.35 pounds for a gallon of water. Milk is 87 % water, thus a gallon of milk will not differ from milk much. The 8.6 lbs/gal factor (whole milk) is correct. The weight increases as fat is removed…
At 20 oC or 293 K or 68 oF, the densities of water and raw milk are 0.998 and 1.03 g/cm3 respectively. As the density of raw milk is slightly more than that of water, 1 gallon of milk will weigh slightly more than 1 gallon of water. However, for practical purposes, it can be considered that, both will weigh the same (as the densities are almost the same).
