Question

consider methane (ch4)
how many molecules of methane do we
have?
how many total carbon atoms do we
have?
how many total hydrogen atoms do we
have?

Explanation:

Step1: Analyze the number of methane molecules

The formula is \(2CH_4\). The coefficient in front of \(CH_4\) represents the number of methane molecules. Here, the coefficient is \(2\).

Step2: Analyze the number of carbon atoms

In each \(CH_4\) molecule, there is \(1\) carbon atom. Since there are \(2\) \(CH_4\) molecules, the total number of carbon atoms is \(2\times1 = 2\).

Step3: Analyze the number of hydrogen atoms

In each \(CH_4\) molecule, there are \(4\) hydrogen atoms. Since there are \(2\) \(CH_4\) molecules, the total number of hydrogen atoms is \(2\times4=8\).

Answer:

• How many molecules of methane do we have? \(2\)
• How many TOTAL atoms of carbon do we have? \(2\)
• How many TOTAL atoms of hydrogen do we have? \(8\)
