Leland Stanford was an industrialist, business tycoon, politician, and the founder of Stanford University. During the California Gold Rush Stanford moved to California and started a whole sale business which grew as the economy boomed. Stanford helped to found a major railroad company the Central Pacific Railroad and went on to make large amounts of money, enough so for many to consider him a "Robber Baron" a name given to wealth and powerful 19th century American businessmen.

Their feet are good for walking on sand.
Camels have always lived in deserts so they are used to living there, they won’t die as easily.
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.
