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.

A social action process that promotes the participation of people, organizations and communities in gaining control over their lives in their community and the larger society is called <u>Revolutionary movements.</u>

Revolutionary movements seek to absolutely alternate each factor of society—their purpose is to trade all of society in a dramatic manner. Examples include the Civil Rights motion or the political actions, consisting of a push for communism.
Thru the dedication and skill of residents, social action can empower groups, assist people in need, and complement public services. Taking part in a social movement is also related to higher tiers of wellbeing, and might enhance humans's self-belief and competencies.
