What unit would be best used to count the number of silver atoms in a spoon?
moles
How many atoms would 3 moles of Ca have?
3 moles of Ca would have 1.806 × 10^24 atoms.
Which of the following electrolytes would you use to electroplate silver Ag on iron Fe A. Zn ClO32 B. AgNO3 C. CuCl2 D. FeSO4?
AgNO3
What would have the greatest mass 1 mole of iron atoms 2 moles of oxygen atoms 4 moles of carbon atoms or 1 mole of potassium atoms?
1 mole of iron atoms has the greatest mass - 55,845 g.
How many moles of Cu are in the 148 times 10 to the power 25 atoms?
15.8 moles Cu x 6.02x10^23 atoms/mole = 9.51x10^22 atoms. There are no molecules in the element Cu (copper). Molecules are found when there are two or more atoms bound together, such as in H2 gas or H2O, etc.
How many mL of .117M AgNO3 solution would be required to react exactly with 3.82 moles of NaCl?
Balanced equation first! AgNO3 + NaCl -> AgCl + NaNO3 all one to one, get moles AgNO3 3.82 moles NaCl (1 mole AgNO3/1 mole NaCl) = 3.82 moles AgNO3 ------------------------------- Molarity = moles of solute/Liters of solution 0.117 M AgNO3 = 3.82 moles AgNO3/Liters Liters = 3.82/0.117 = 32.6 Liters which is 32600 milliliters which is unreasonable; check answer if you can
How many moles of silver nitrate would be required to react with 2.00 moles of sodium phosphate?
I assume double displacement reaction. Balanced equation. 3AgNO3 + Na3PO4 -> Ag3PO4 + 3NaNO3 2.00 moles sodium phosphate ( 3 moles AgNO3/1 mole Na3PO4) = 6.00 moles silver nitrate needed =========================
A smaple of silver with the same mass as the earth would contain how many atoms of silver and how many moles of silver?
its 125,524,727,836
What unit would be best used to count the number of silver atoms in a spoon?
moles
Which of the following electrolytes would you use to electroplate silver (Ag) on iron (Fe)?
agno3
What electrolytes would you use to electroplate silver Ag on iron Fe?
AgNO3
How many atoms in 10 moles of na?
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
How many atoms would 3 moles of Ca have?
3 moles of Ca would have 1.806 × 10^24 atoms.
Which of the following electrolytes would you use to electroplate silver Ag on iron Fe A. Zn ClO32 B. AgNO3 C. CuCl2 D. FeSO4?
AgNO3
What does a googol of atoms equal?
One googol of atoms would be 10100 atoms or 1.66 × 1076 moles.
What is the mass of silver bromide precipitated from 2.96 g of iron bromide?
This is an incomplete question for several reasons. Iron bromide can be FeBr2 or FeBr3 and this will influence the answer. Also, in order to precipitate silver bromide, one would add silver nitrate, but it isn't stated how much silver nitrate is used. Assuming FeBr2 is used, and there is excess AgNO3, then .... 2AgNO3 + FeBr2 ----> 2AgBr(s) + Fe(NO3) moles FeBr2 = 2.96 g x 1 mol/216 g = 0.0137 moles moles AgBr produced = 2 x 0.0137 = 0.0274 moles mass AgBr produced = 0.0274 moles x 188 g/mole = 5.15 grams <---answer
How much silver in silver nitrate?
the compound is chemically AgNO3, by mass, that would mean silver nitrate is 63% elemental silver. By volume, silver is denser than nitrogen or oxygen and would be less than 63%.
