What metric unit is a grain of salt?
It depends on whether you wish to measure its length, its volume or its mass.
Why does one teaspoon of salt and one teaspoon of sugar weigh the same?
Even though salt and sugar have different chemical compositions, they both have similar densities. This means that a teaspoon of salt and a teaspoon of sugar will weigh the same because they take up the same volume.
If a typical grain of salt has a mass of 0.3 mg how many unit cells does it contain?
the weight of a grain of salt is about 5.85x10-5 gramsApproximately how many atoms are in a grain of salt?Asked by: Roger Bevels (teacher)AnswerThis is mainly an estimation problem -- there is no exact measure of how big a 'grain of salt' is. So, the answer will be only correct within an order of magnitude (a factor of 10).The first step is to estimate how large a grain of salt is. I spilt some salt onto the table, and visually estimated that about three grains of salt placed end-to-end are about a millimeter long. (Your mileage may vary.) So, as a simple estimate, I'll assume that salt grains are 0.3 millimeters long.The next assumption is that salt crystals are cubes, with 0.3 millimeter sides. In fact they tend to be, since the crystal structure of NaCl is cubic. However, most have broken corners, but we will ignore that.The density of NaCl is about 2.165 gr/cm3. With the cube assumption, we find that a grain of salt is about 5.85x10^-5 grams. (We could have arrived at this result by weighing an individual grain, or by weighing a gram and then counting the number of grains in it, but this is left as an exercise for the PhysLink reader.)The next thing we need is the weight of a 'salt atom'. There is no such thing as a salt atom, it consists of Na (sodium) and Cl (chlorine) atoms. So, we need to use an average value. The atomic mass of Na is 23 gr per mole, and the atomic mass of Cl is 35.5 gr per mole. So, the average 'atomic weight of salt' is 29.25 grams per mole.Now it is a simple matter to find how many atoms there are in a grain of salt. (Note that one mole contains Avogadro's number of atoms, which is 6.02x1023.)So a grain of salt contains about:5.85x10-5 gr/ (29.25 gr / 6.02x1023) = 1.2x1018 atoms, half of which are sodium atoms. (The other half is chlorine atoms, of course.)Answered by: Yasar Safkan, Ph.D. M.I.T., Software Engineer, Istanbul, Turkey
How many pounds is a gallon of salt?
It's difficult to say for sure. Salt comes in different sizes of grains therefor you'd really have to have a solid chunk of salt that is exactly one gallon in size and weigh it to know for sure.I've seen figures stating that 1 cubic yard of rock salt = 2160lbsAccording to Google, 1 cu yard = 201.974 US gallonsSo if 2160 lbs of Salt = 201.974 US Gallons then 2160/201.974 = 10.694 lbs/US Gal.As stated above, this is not exact but will get you close. Hope this helps.
How much does one cup of salt water weigh?
It will depend on how salty it is as the salt affects the density. 1 US cup = 236.588238 ml The density of pure water is exactly 1 gram per ml at 4 °C, and so 1 cup would weigh exactly 236.588238 g, or 8.345 oz (1 gram = 0.0352739619 ounces). The more salt you add, the higher the density, and the more 1 cup of salt water would weigh. Ocean water is only slightly more dense than pure water (approx. 1.026 grams per mL), although its density actually depends on how deep you are (it varies between 1.025 at the surface to 1.028 below 1000 meters). And so, to a close approximation 1 cup of ocean water would weigh 242.7 g, or 8.55 oz.
How much does a grain weigh?
Assuming you mean the obsolete mass unit rather than a grass seed. one grain is 64.799 milligrams.
Is a grain a tiny piece of rock?
A grain can be a tiny piece of rock, yes. A grain can also be a grain of salt, meaning one 'pellet' of salt.
How much does one pound of salt weigh?

How much does one cc of salt weigh?
One cubic centimeter (cc) of salt typically weighs about 2.16 grams.
How much does one peck of seed weigh in pounds?
One peck of grain is equivalent to two gallons or 8 quarts so it's hard to say exactly how much one peck weighs in pounds. It depends on the type of grain.
What is one piece of salt called?
A single piece of salt is called a grain or a crystal.
How much does one billion grains of sand weigh?
On average, a grain of sand weighs about 0.25 milligrams. Therefore, one billion grains of sand would weigh around 250 kilograms.
How much does a grain of rice weigh in grams?
Since one grain of rice weighs between 20-30 mg, it weighs about .2-.3 grams.
What metric unit is a grain of salt?
It depends on whether you wish to measure its length, its volume or its mass.
What is a piece of sugar called?
One piece of sugar is a grain, which is also the same for salt. E.g., a grain of sugar or a grain of salt.
