Answer:
9 grams of methane contains a greater number of hydrogen atoms (therefore molecules) than 10 grams of ammonia
Explanation:
The number of atoms of hydrogen per molecule of ammonia = 3 atoms of hydrogen
The number of atoms of hydrogen per molecule of methane = 4 atoms of hydrogen
The molar mass of methane = 16.04 g/mol
The molar mass of ammonia = 17.031 g/mol
The number of moles of methane in 9 grams of methane = 9/16.04 ≈ 0.561 moles
The number of hydrogen atoms in 0.561 moles of methane = 0.561 × 6.02 × 10²³ × 3 ≈ 1.351 × 10²⁴ atoms of hydrogen
The number of moles of ammonia in 10 grams of ammonia = 10/17.031 ≈ 0.5872 moles
The number of hydrogen atoms in 0.5782 moles of ammonia = 0.5872 × 6.02 × 10²³ × 3 ≈ 1.06 × 10²⁴ atoms of hydrogen
Therefore, 9 grams of methane contains a greater number of hydrogen atoms than 10 grams of ammonia.
Answer:
Alexander's death was sudden and his empire disintegrated into a 40-year period of war and chaos in 321 BCE. The Hellenistic world eventually settled into four stable power blocks: the Ptolemaic Kingdom of Egypt, the Seleucid Empire in the east, the Kingdom of Pergamon in Asia Minor, and Macedon.
After the death of Alexander the Great in 323 B.C., anti-Macedonian sentiment again forced Aristotle to flee Athens. He died a little north of the city in 322, of a digestive complaint. He asked to be buried next to his wife, who had died some years before.
