This decrease in volume is called contraction.”, Properties of Matter  Smithsonian Institution National Science Resource Center, “The density of ice is about 90 percent that of water, but that can vary because ice can contain air, too. The density of water is 1 kilogram per liter (kg/L) at 39.2°. Find out more about how we use your information in our Privacy Policy and Cookie Policy. While a waterbed weighs less per square foot than a refrigerator, the amount of water contained in a king-size waterbed can produce a total weight of approximately 1,500 pounds. Although waterbeds go in and out of vogue, there is no doubt that they represent one of the most common tactile household experiences of water weight. … What’s more, if water is heated from room temperature, 70°F to its boiling point of 212°F, it will weigh 7.996 pounds, losing .333 pounds. Given that a molecule of hydrogen weighs 1.01 Atomic Mass Unit (AMU) and one molecule of oxygen weighs 16 AMUs, the molecular weight of water is 18.02 AMUs. Does Hot Water Freeze Faster Than Cold Water? Favorite Answer. Tro, Nivaldo J., and Don Neu. That means that about 10 percent of an ice cube (or iceberg) will be above the water line.”. To enable Verizon Media and our partners to process your personal data select 'I agree', or select 'Manage settings' for more information and to manage your choices. One cup of water weighs approximately 8 ounces, which is equal to 225 grams. How Much Does Water Weigh?The most widely accepted simple scientific answer to this question is that a gallon of room temperature water weighs 8.33 pounds. Answer Save. Information about your device and internet connection, including your IP address, Browsing and search activity while using Verizon Media websites and apps. Cambridge Dictionary, “Most matter increases in volume when it gets hotter. Chemistry in Focus: a Molecular View of Our World. You can change your choices at any time by visiting Your Privacy Controls. When cooled down, most matter decreases in volume and increases in density. 50 pounds divided by 2.2 (kilo) = 22.72 lires of water. The weight of water can also be quantified by its molecular weight, the sum of the atomic weights of the atoms in a single molecule. Oxford Dictionary, Molecular Weight: the weight of a molecule, found by adding together the atomic masses of all the atoms it contains; relative molecular mass. Atomic Mass Unit: unit of mass for expressing masses of atoms, molecules, or nuclear particles that is equal to 1/12 of the atomic mass of the most abundant kind of carbon. I am wanting to purchase a shopping cart that will hold 2 or 3 24 bottles/pack of water from car. The weight of a volume of water can be found given the density, which is the mass compared to the volume. US Department of Interior Geological Survey, USGS Georgia Water Science Center – Water Density, National Institute of Standards and Technology – Atomic Weights and Isotopic Compositions for All Elements, My Waterbed Shop – How Much Does a Waterbed Weigh, Weight: 62.416 pounds per cubic foot at 32, Weight: 61.998 pounds per cubic foot at 100, Density: 1 gram per cubic centimeter (cc) at 39.2. One fluid ounce of water weighs about 1.043 ounces. However, if the six pack is 12-oz cans, it would weigh 72 ounces or 4.5 pounds. This happens because the mass of the rod stays the same, but its volume increases. The standard atomic weight for oxygen is 15.994(3) [4], Source: US Department of Interior Geological Survey. is equal to 2.2 lbs. We and our partners will store and/or access information on your device through the use of cookies and similar technologies, to display personalised ads and content, for ad and content measurement, audience insights and product development. 35 x ½ liter = 17.5 liters = 17.5 kg. 1 kg. The density of water is 1g/cm^3 or 1 kg per 1 liter. For example, if an iron rod is heated, it will get longer and fatter and its density will decrease. When water is heated the hydrogen and oxygen molecules begin to vibrate more quickly and begin to move farther apart. Relevance. So, to get your answer you would multiply 16.9 by 1.043. Yahoo is part of Verizon Media. Richard. What's more, if water is heated from room temperature, 70°F to its boiling point of 212°F, it will weigh 7.996 pounds, losing .333 pounds. There is even a popular reoccurring feature on The Late Show, “Will It Float?”, wherein David Letterman and sidekick Paul Schaeffer try to guess whether or not a particular item will stay on top of the water surface or drop like a stone to the bottom. The standard atomic weight for hydrogen is 1.00794(2). One cup holds 225 milliliters of water. Boston, MA: Brooks/Cole, Cengage Learning, 2009. Q: How much does a pack of 24 bottles of 16.9 oz bottled water weigh? Note: For ease in understanding the concept, the atomic weights have been rounded. Lv 7. This means that 1 liter (L) of water weighs 1 kilogram (kg) and 1 milliliter (mL) of water weighs 1 gram (g). Though almost negligible, this will increase its volume and decrease its density.
