Balanced equation. Fe(OH)3 + 3HNO3 --> Fe(NO3)3 + 3H2O 63.8 grams Fe(NO3)3 (1 mole Fe(NO3)3/241.88 grams)(1 mole Fe(OH)3/1 mole Fe(NO3)3 = 0.264 moles iron III hydroxide needed ==========================
122 grams of anhydrous Cu(NO3)2 contain 3,92.10e23 molecules.
The number of molecules is 12,044280.10e23.
13.5g Mg(NO3)2 x 1 mol Mg(NO3)2/148.3 = 0.0910 mol Mg(NO3)2
For this you need the atomic (molecular) mass of Hg(NO3)2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Hg(NO3)2=324.6 grams8.50 grams Hg(NO3)2 / (324.6 grams) = .0262 moles Hg(NO3)2
Fe(NO3)2molecular weight. Molar mass of Fe(NO3)2= 179.8548 g/mol. This compound is also known as Iron(II) Nitrate. Convert grams Fe(NO3)2to moles or moles Fe(NO3)2to grams.
Quite a few! 698 grams Al(NO3)3 (1 mole Al(NO3)3/213.01 grams)(9 moles O/1 mole Al(NO3)3)(6.022 X 1023/1 mole O) = 1.78 X 1025 atoms of oxygen ======================
The species is; Ca(NO3)2 ( NO3(-) is a polyatomic ion and is in parenthesis ) 7.5 grams Ca(NO3)2 (1 mole Ca(NO3)2/164.1 grams)(2 mole N/1 mole Ca(NO3)2)(6.022 X 10^23/1 mole N) = 5.5 X 10^22 atoms of nitrogen
Ca(NO3)2Number of atoms in the compound:Ca- 1N- 2O- 6Find the atomic masses of all atoms and add:Ca = 40.1N = 2 * 14.0 = 28.0O = 6 * 16.0 = 96.0___________________164.1 gEquation:# moles * added atomic mass = # gramsAnswer:4.2 moles * (164.1 g) = 689.22 grams of Ca(NO3)2
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 -----------------------------------------------
