How many atoms in 3CaCl2?
There are a total of 13 atoms in 3CaCl2: 3 calcium atoms and 6 chlorine atoms.
How many times larger is the number of hydrogen atoms than oxygen atoms in disaccharide?
the basic formula is C6H12O6, so there are twice as many number of hydrogen-to-oxygen atoms. This applies to carbon atoms as well when compared to hydrogen atoms.
How many moles are in 2.16 10 to the 24 power atoms of iron?
To calculate the number of moles from the number of atoms, we need to divide the number of atoms by Avogadro's number (6.022 × 10^23), which gives 3.59 moles of iron atoms.
How many times larger is the number of hydrogen atoms then oxygen atoms in all carbohydrates?
The number of hydrogen atoms is typically twice the number of carbon atoms in carbohydrates, while the number of oxygen atoms is similar to the number of carbon atoms. Therefore, the number of hydrogen atoms is usually larger than the number of oxygen atoms in carbohydrates.
What type of number after a chemical symbol tells how many atoms are in a single molecule?
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
How many grams of plaster of Paris are in 8 ounces?
There are approximately 226.8 grams in 8 ounces of plaster of Paris.
How many cups in 1 pound of plaster of Paris?
About 1.74 cups
Why is plaster of Paris named plaster of Paris?
ANSWERS any of several gypsum cements; a white powder (a form of calcium sulphate) that forms a paste when mixed with water and hardens into a solid; used in making molds and sculptures and casts for broken limbs
How many mililitres in 100 grams for plaster of Paris?
Well, isn't that a lovely question! The conversion of grams to milliliters can be a bit tricky because it depends on the density of the substance. For plaster of Paris, it's typically around 0.86 grams per milliliter. So, for 100 grams of plaster of Paris, you'd have roughly 116 milliliters. Just remember, it's always good to double-check with the specific product you're using for the most accurate measurement.
How does a number of H Atoms in a carbohydrate compared to the number of oxygen atoms?
It depends on how many hydrogens are there and how many oxygen atoms there are.
How do you tell how many atoms there are in a single unit?
you subtract the atomic number by the number of atoms
How many total atoms are in Na2H3IO?
The number of atoms is seven.
How many atoms are in g Pb?
The number of atoms of lead is 6,68.10e23.
How do you dissolve plaster of Paris?
"I think vinegar is supposed to work.Lawren1The CRC Handbook of Chemistry and Physics (65th ed. Special:Booksources) lists plaster of Paris (calcium sulphate half-hydrate, CaS04.1/2H2O) as soluble in acid, ammonium salts, sodium thiosulphate (Na2S2O3) and glycerin."I am so surprised that so many people on so many forums, obviously don't have a clue about the chemistry of plaster of Paris. I read in so many places things like "uh, try some kind of acid..."So I have a lot of concentrated chemicals on hand and did lots of experiments with all kinds of acids, both dilute and concentrate, under many conditions and determined that none of my dozen or so acids dissolve Plaster of Paris in any way, but sometimes make it harder.The chemicals which dissolved plaster of Paris are on the basic end of the PH scale, not acid. I first had some success with potassium cyanide, but what really worked better than anything is Sodium Bicarbonate. Makes sense. The sodium in baking soda hooks up with sulfur in the plaster, and the carbon hooks up with the calcium in the plaster.TO BEST DISSOLVE PLASTER OF PARIS PLACE IT IN WARM WATER WITH LOTS OF BAKING SODA.Don't use any acids or it will only defeat the process.Now what really amazes me is that the answer is so simple and safe, and surely some people must know it, but it apparently cannot be found on the internet, until now.Or you can chisel it away because it is soft enough to do so.
How many moles of atoms are in 450000000000000000000000 atoms of Cu?
Divide that number of atoms by 6.02x10^23 atoms/mole
How many atoms are in heptane?
Heptane has a chemical formula of C7H16. To calculate the number of atoms in heptane, add the number of carbon atoms (7) to the number of hydrogen atoms (16), resulting in a total of 23 atoms in heptane.
How many atoms are in 4.2 moles of potassium nitride?
The number of atoms is 101,341.10e23.
