Question

1. the chemical formula for methane is $\text{ch}_4$.

which statement describes the atoms present in four molecules of methane?
four molecules of methane would contain 1 atom of carbon and 4 atoms of hydrogen.
four molecules of methane would contain 4 atoms of carbon and 16 atoms of hydrogen.
four molecules of methane would contain 16 atoms of carbon and 16 atoms of hydrogen.
four molecules of methane would contain 4 atoms of carbon and 1 atom of hydrogen.
clear all

Explanation:

Step1: Identify atoms per methane molecule

1 molecule of $\text{CH}_4$ has 1 C atom and 4 H atoms.

Step2: Calculate total C atoms for 4 molecules

Total C atoms = $4 \times 1 = 4$

Step3: Calculate total H atoms for 4 molecules

Total H atoms = $4 \times 4 = 16$

Answer:

Four molecules of methane would contain 4 atoms of carbon and 16 atoms of hydrogen.
