Answer C) 6 × 1023 atom
The number of silver atoms present in one mole of silver is 6.0 × 10²³ atoms. The correct option is C) 6 × 1023 atoms
StoichiometryFrom the question, we are to determine the number of silver atoms present in one mole of silver.
From the formula,
Number of atoms = Number of moles × Avogadro's constant
Number of atoms = 1 × 6.022 × 10²³
Number of atoms = 6.022 × 10²³
Number of atoms ≅ 6.0 × 10²³ atoms
Hence, the number of silver atoms present in one mole of silver is 6.0 × 10²³ atoms. The correct option is C) 6 × 1023 atoms

Using the balanced chemical equation:
4NH3 + 302 --> 2N2 + 6H20
Determine the amount of grams of N2 is produced If 4.03 moles of NH3 react?
Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.
Reaction stoichiometryIn first place, the balanced reaction is:
4 NH₃ + 3 O₂ → 2 N₂+ 6 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
NH₃: 4 molesO₂: 3 molesN₂: 2 molesH₂O: 6 molesThe molar mass of the compounds is:
NH₃: 17 g/moleO₂: 32 g/moleN₂: 28 g/moleH₂O: 18 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
NH₃: 4 moles ×17 g/mole= 68 gramsO₂: 3 moles ×32 g/mole= 96 gramsN₂: 2 moles ×28 g/mole= 56 gramsH₂O: 6 moles ×18 g/mole= 108 gramsMass of N₂ formedThe following rule of three can be applied: if by reaction stoichiometry 4 moles of NH₃ form 56 grams of N₂, 4.03 moles of NH₃ form how much mass of N₂?
[tex]mass of N_{2} =\frac{4.03 moles NH_{3} x56 grams of N_{2} }{4 moles NH_{3}}[/tex]
mass of N₂= 56.42 grams
Then, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.
