The amount ( in moles  of excess  reactant that is left is 0.206 moles


Explanation

FeS(s)  + 2HCl  (aq) →  FeCl2 (s)  + H2S (g)

  • by use of mole ratio of FeS: HCl which is  1:2 this means that  0.223 mole  of FeS  reacted  completely with 0.223   x   2/1 =0.446  moles  0f FeCl2.

  • HCl was in  excess because  0.446 moles of HCl reacted and initially  there was  0.652  moles.
  • Therefore the  amount that was left

      = 0.652- 0.446  =0.206  moles

How many atoms of N are in 137.0 grams of N2O3?
olasank [31]

Answer: The number of N atoms in 137.0 g of N2O3 21.67 x 10∧23 atoms.

Explanation:

  • We must obtain the number of moles of the compound: (n = mass/molar mass), mass = 137.0 g and molar mass of N2O3 = 76.01 g/mol.
  • n = (137.0 g)/ (76.01 g/mol) = 1.80 mol.
  • It is necessary to determine the number of molecules of this sample.
  • Every mole contains Avagadro's number (6.02 x 10^23) of molecules.
  • The number of molecules = (6.02 x 10^23)(1.80) = 10.84 x 10∧23 molecules.
  • Every molecule of N2O3 contain 2 atoms of N.
  • The number of N atoms in 137.0 g of N2O3 = (10.84 x 10∧23 molecule) (2 atoms) = 21.67 x 10∧23 atoms.
