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.

Explanation:
Hay una idea sobre la religión que puede incomodar tanto a ateos como a creyentes. Su universalidad hace pensar que está inscrita en el cerebro humano gracias a la selección natural, porque cumple alguna función que ayudó a los creyentes a sobrevivir. Los humanos habríamos evolucionado para crecer con el germen de la fe en algún tipo de dios o dioses, del mismo modo que, según planteó Noam Chomsky hace décadas, los niños vienen al mundo con estructuras neuronales que les permiten aprender el idioma de sus padres. Después, el entorno es el que determina el lenguaje o la religión particular que se aprende.
