Answer:
152.4 g
Explanation:
Step 1: Given data
Number of H atoms: 8.334 × 10²⁴ atoms
Step 2: Calculate the moles of H corresponding to 8.334 × 10²⁴ atoms of H
We will use Avogadro's number, that is, there are 6.022 × 10²³ atoms of H in 1 mole of H.
8.334 × 10²⁴ atom × (1 mol/6.022 × 10²³ atom) = 13.84 mol
Step 3: Calculate the moles of ammonium acetate (NH₄CH₃CO₂) that contain 13.84 moles of H
The molar ratio of NH₄CH₃CO₂ to H is 1:7. The moles of NH₄CH₃CO₂ that contain 13.84 moles of H are 1/7 × 13.84 mol = 1.977 mol.
Step 4: Calculate the mass corresponding to 1.977 moles of NH₄CH₃CO₂
The molar mass of NH₄CH₃CO₂ is 77.08 g/mol.
1.977 mol × 77.08 g/mol = 152.4 g
4) Example of physical properties: colour, Smell, texture, boiling and melting point density and viscosity.
11) Cations are formed when positively-charged ions and anions negatively-charged ions are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.
12) Quantum mechanical model: The Quantum Mechanical Model. ... The quantum mechanical model of the atom uses complex shapes of orbitals (sometimes called electron clouds), volumes of space in which there is likely to be an electron.

The Nuclear Model-1909. Ernest Rutherford's great contribution to atomic theory was to show what happens to an element during radioactive decay. This enabled him to construct the first nuclear model of the atom, a cornerstone of present-day physics The Nuclear Model-1909.
