What is the difference in weight between a gallon of salt water and a gallon of fresh water?
salt water has more mass because of the added salt so salt is heavier :)
What percentage of the worldswater is salt water?
97% of the worlds water is Salt water. 71% of the world is Covered by Saltwater.
What are the probable sources of salt in the atmosphere?
the ocean. water from the ocean evaporates into the air, ocean water has salt in it.
How many milligrams of salt must be added to 18 milligrams of a 20 percent salt solution to obtain a 35 percent salt solution?
this question is not hard to answer, but it does require that one make some assumptions. The simplest answer assumes that the 20% salt solution refers to per cent by mass. Thus: a 20% salt solution is one which contains 20 mg salt for every 100 mg solution where the solution consists of a mixture of 20 mg salt plus 80 mg water. A 35% salt solution would contain 35 mg salt for every 65 mg water. Now, assuming that all the water in 18 mg of a 20% salt solution remains in the final solution we see that 18 mg salt solution x 20 mg salt/100 mg salt solution gives 3.6 mg of salt; thus, there are 18 mg total solution - 3.6 mg salt = 14.4 mg water. So the final salt solution must be one that contains 14.4 mg water and enough salt to make it 35% salt by mass. Mathematically, this is written as Z mg salt/(Z mg + 14.4 mg water) = 35/100 This gives Z = 0.35*(Z + 14.4) or Z = 0.35*Z + 0.35*14.4 which is same as Z = 0.35*Z + 5.04 and 0.65*Z = 5.04 so Z = 5.04/0.65 = 7.75 mg total salt needed. We started with 3.6 mg salt, so we must add 7.75 -3.6 = 4.15 mg salt Check: 7.75 mg salt/(7.75 mg salt + 14.4 mg water) = 0.35 or 35% There you go! --assuming that much salt dissolves that amount of water!
How many cubic inches of salt does a container with a diameter of 6.28 and a height of 6 inches contain?
diameter = 6.28 inches => radius = 3.14 inches Then volume = pi*r2*h = pi*3.142*6 = 185.85 cubic inches.
What does a cubic meter of salt weigh?
The weight of a cubic meter of salt can vary depending on the type of salt. On average, the weight of a cubic meter of salt is around 2,165 kilograms.
How much does sea water weigh per cubic foot?
The weight of sea water really depends on a number of variables, including the temperature, the amount of salt (salinity) and whatever other foreign items may be present, and the depth, thus the pressure. But to get to the basic answer, seawater, at the surface, on average weighs 1027 kg/m3, or just over 64.1 lbs per cubic foot. ----------- The question is another way of asking for density of salt water. Salt water has greater density than that of fresh water, due to the dissolved salt. Fresh water has a density of 1000 kg/cubic meter vs. an average density of 1027 kg/cubic meter for ocean salt water.
What is the density of a salt solution compared to water?
The density of a salt solution is higher than that of water due to the additional weight of the dissolved salt particles in the water. The exact density of the salt solution will depend on the concentration of the salt in the solution.
How much does 1 liter of salt water weigh in kg?
The density of seawater varies from 1020 to 1029 kg/cubic meter, with 1027 kg/cubic meter being cited most often for water at the ocean's surface. There are 1,000 liters per cubic meter, so the density of seawater can also be expressed as 1.027 kg/liter (for surface seawater). Thus 1 liter of seawater will weigh 1.027 kg.
What is the weight of 11 cubic feet of water?
11 cubic feet of plain (non-salt) water weighs approximately 686.7 pounds or 311.5 kilograms.
How much is ocean or salt water?
There are a number of variables which will determine the exact weight. It is generally accepted that the weight is 64lbs per cubic foot
How does the density of fresh water compare to the density of salt water?
Yes, fresh water of 10 degrees Celsius has a density of 999.728 kilograms per cubic meter. Seawater of 10 degrees Celsius and of 3.5 % salinity has a density of 1026.978 kilograms per cubic meter.
How can salt change Density?
Fresh water at a temperature of 10 degrees Celsius has a density of 999.70 kilograms per cubic meter or 0.9997 grams per cubic centimeter. Sea water with a salinity of 3.5 percent at a temperature of 10 degrees Celsius has a density of 1026.98 kilograms per cubic meter or 1.02698 grams per cubic centimeter.
Can a penny float in salt water?
A penny as everyone I'm sure knows cannot float in regular water. As for salt water a penny should in theory not be able to becase the regular pennys bouancy is not great enough to support the weight of the penny regardless of the salt to water ratio. A penny is too dense to be able to float in salt water, regardless of the salinity of the solution.
How many pounds does sea water weigh per cubic foot?
About 2.2 pounds of salt in a cubic foot of sea water. There are about 7.48 gallons in a cubic foot and sea water weighs about 8.5 pounds per gallon (63.58 pounds). Sea water is about 3.5 % salt (usually reported as 35 ppt or parts per thousand). So 63.58 x .035 = 2.2 pounds of salt.
What is a desa liter?
A desaliter is a unit of measurement used to quantify the salt content of water or other liquids. One desaliter is equal to 10 grams of salt per cubic meter of water.
Why is salt water heavier then tap water?
because salt has weight
