This is the standard value used by scientists to determine the specific gravity of various substances. The specific gravity of water is one at 4 degrees Celsius. As a result, it is a relative quantity that lacks units. The specific gravity of a material is defined as the ratio of its density to that of water at 4 ☌ (where it is most dense and is taken to have a value of 999.974 kg m -3). One mole of water equals to18ml of water. Volume = 1 gram per milliliter/18.0152 g = 18ml. Mass of 1 mole of water = mass of hydrogen + mass of hydrogen + mass of oxygen. One mole of water is 6.022 x 10 23 water molecules. Therefore, the density of the cold water is greater than it would be in the hot water. This results in a decrease in the density of water. Therefore, the amount of space each molecule needs is greater. When we heat up water, we increase the energy of water molecules.Īs a result, the kinetic energy of water molecules increases, and they get more spaced out. The Effect of Temperature on the Weight of WaterĮven moderate fluctuations in temperature do affect the weight of water. How many liters are in cubic centimeters?ġ cm 3 = 10 -3 liters. The density of water in g/ml is around 1 gram per milliliter at 17 ✬. If we turn the heating way up to 200✯ though, a gallon of water will weigh around 8.04 lbs.Īt room temperature (70☏ or 21☌), a US gallon of water weighs 8.33 lbs (3.78kg). Water has a maximum density at 39.2✯ or 4✬.Īt this temperature, a gallon of water weighs around 8.345 lbs. The temperature of the water can affect the density of the water. How many liters of water make a gallon?ġ Gallon = 4.54609 Liters Effect of Density on Water Weight A British pint has twenty fluid ounces, whereas an American pint contains sixteen. A fluid ounce is a unit of liquid measurement. A cup holds 8 fluid ounces, whereas a liter holds 33.8 fluid ounces. There are three different units of a gallon: Weight of a Gallon of Waterġ litre (or liter, in the US) = 0.264172 US gallonġ liter = 4.16667 cups How many cups are in a liter?Ī liter contains 4.227 cups. Mass = density x volume = 0.99802 g/cm3 x 1000 cm3 = 998.02 grams = 1000 grams (rounded value)ġ liter of water = 35.274 ounces. The Effect of Temperature on the Weight of WaterĪt 17 degrees Celsius, the density of water is 0.99802 g/cm 3.How many liters are in cubic centimeters?.How many liters of water make a gallon?.As per the density definition, the weight of the water can be calculated by multiplying the density of water by the volume of water.ġ gram = 0.035274 ounces (oz) = 0.001 kilograms (kg) = 0.00220462 pounds (lb) Volume The weight of water depends upon the temperature of the water, For the sake of the question, “How much is a liter of water?”, we are using the density value of water as 0.99802 g/cm 3 ( rounded value of 1 g/cm 3) at 17 ☌. Specific gravity is a ratio and has no units. The specific gravity of water is 1 at 4 degrees Celsius. 1 liter of waterġ000 grams, 35.274 ounces, or 0.264 US gallons A liter is 1000 milliliters, or roughly 0.03338 gallons or 0.00338 cubic centimeters. A liter is a volume unit defined as the volume of one kilogram of pure water. In addition, it’s important to define a liter here. Furthermore, if we consider the capacity of a glass of water to be equal to 8 ounces, then 1 liter of water is equal to 4.40 glasses (32 ounces). A liter of water equals 1000 grams, 35.274 ounces, 0.264 US gallons, or 4.2 US cups (236.59 milliliters) at 17 ☌.
