How many atoms does Calcium Nitrate have?
6,022 x 1023 atoms/mole. Calcium nitrate = Ca(NO3)2 .There are 1 mole of calcium making 6,022 x 1023 atoms of calcium.There are 2 moles of nitrate-ions and each nitrate-ion is made up of 1 mole nitrogen, and 3 moles of oxygen. Thath means that the nitrate ion in calcium nitrate has 6 moles oxygen and 2 moles of nitrate:Atoms of nitrogen: 6,022 x 1023 moles-1 x 2 moles = 1,2044 x 1024 atomsAtoms of oxygen: 6,022 x 1023 moles-1 x 6 moles = 3,6132 x 1024 atoms
How many moles of ZnCl2 will be produced from 23.0 g of Zn?
Atomic mass from my Periodic Table for Zinc is 65.38. This means 1 mole of naturally occurring zinc has a mass of 65.38 grams. If your zinc sample is pure zinc then: (mass of your sample)/(65.38 grams) = # moles of zinc.
How many moles of HCl are needed to react with 2.3 moles of Zn in the following reaction?
I assume you mean this reaction. Zn + 2HCl --> ZnCl2 + H2 2.3 moles zinc (2 moles HCl/1 mole Zn) = 4.6 moles hydrochloric acid needed ========================
How many grams of hydrochloric acid are reacted when 1.80 mol of zinc is reacted with 7.10 mol of hydrochloric acid?
A lot of that hydrochloric acrid is excess and some grams will not react, I think. Balanced equation first. Zn + 2HCl -> ZnCl2 + H2 Check to make sure of limiting reactant; I suspect zinc. 1.80 moles Zn (2 mole HCl/1 mole Zn) = 3.60 moles HCl You have a lot more than that, Zn limits and will drive the reaction 1.80 moles Zn (2 moles HCl/1 mole Zn)(36.458 grams/1 mole HCl) = 131 grams of hydrochloric acid reacted with that Zinc amount ----------------------------------------------------------------------------------
How many moles are in 1 kg of CF2Cl2?
1 kg of difluorodichloromethane is equivalent to 8,27 moles.
When a strip of zinc is placed in a solution of silver nitrate Zn replaces Ag to form zinc nitrate and metallic silver is formed How many moles of silver will be generated if 1 point 30 moles of Zn?
As shown by the ionic equation of the reaction, Zn (s) + 2 Ag+ (aq) --> 2 Ag (s) + Zn2+ (aq), each mole of zinc produces two moles of silver. Therefore, 1.30 moles of zinc will displace 2.60 moles of silver.
How many moles are in 125g of Zn?
The equivalent of 125 g zinc is 1, 91 moles.
How many moles of nitrogen are there in 3 moles of ammonium nitrate?
The volume occupied by 3 moles of nitrogen gas will be different, depending on the temperature and pressure of the gas.
What is the chemical name Zn(NO3)2?
For clarity, zinc (II) nitrate would be the preferred name. However, if you just said "zinc nitrate", most chemists would guess you meant that formula; the +1 oxidation state is technically possible for zinc, but zinc (I) compounds are relatively rare.
How many moles for silver chloride are produced from 7 mol of silver nitrate?
Since both chloride anions and nitrate anions have a charge of -1, there will be the same number of moles of silver chloride produced as the moles of silver nitrate reacted. (Since both silver nitrate and silver chloride are ionic compounds, it would be preferable to call their "moles" "formula units" instead.)

How many moles in 4.50 grams of silver nitrate?
4.50 g(1/169.88) =.0265 mols
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 =========================
What elements are present in zinc nitrate?
Zinc nitrate ( Zn(NO3)2) has the elements, zinc, nitrogen and oxygen.
How many moles of zinc Zn are in 1.33 1024 Zn atoms?
6,022140857.10e23--------------1 mol1,33.10e24----------------------------xx = 1,33.10e24/6,022140857.10e23 = 2,2 moles Zn
How many moles of hydrogen will be produced if 0.36 moles of zinc react with an equal amount of H2SO4?
Zn + H2SO4 ---> ZnSO 4 + H2 so one mole of zinc and 1 mole of sulfuric acid produces one mole of hydrogen molecules and thus two moles of hydrogen atoms. So 0.36 moles of zinc will produce 0.36 moles of hydrogen molecules and thus 0.72 moles of hydrogen atoms.
How many moles of magnesium nitrate are produced when magnesium reacts with 8 moles of nitric acid?
Mg2+(s) + 2HNO3(l)= Mg(NO3)2(aq) + H2(g) since the only mole value given is 8 I must assume this is the limiting reactant. Because of the 2:1 ratio of Nitric acid to Magnesium Nitrate, meaning there must be 2 moles Nitric acid for every 1 mole Magnesium Nitrate formed, 4 moles of Magnesium nitrate will be formed.
