Ca(NO3)2
5.600 grams calcium nitrate ( 1mole Ca(NO3)2/164.1 grams)(2 moles NO3/1 mole Ca(NO3)2)
= 6.825 X 10 -2 moles of nitrate ions

Good luck on the Chem packet lol
Calcium Nitrtae is Ca(NO3)2 and so there are two moles of nitrate per mole of calcium nitrate. Thus there are 2 x 2.50 = 5.0 moles of nitrate present.
How many MOLES of sodium nitrate are present in 2.85 grams of this compound ?
there are two moles produced in potassium nitrate.
2.0^25 moles of silver nitrate is .0301 moles.
0.0999458293608 moles

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
0.5 = moles calcium nitrate / 3 L 0.1667 moles Ca(NO3)2 0.1667 * 148 = 24.7g Ca(NO3)2
7,68 grams of calcium nitride is equal to 0,052 moles.
Ca (NO3)2 So the number of Ca atoms will just be Avogadro's constant, L
The molecular weight of Calcium Bromide is extremely close to 200. So 1200/200 = 6 moles present.
there are two moles produced in potassium nitrate.
There are 0.13 moles in 20 grams of magnesium nitrate.
2.0^25 moles of silver nitrate is .0301 moles.
9 moles of Fe(No3)
0.5 moles of Ca2+1 mole of CN-
