Question

how many moles of h are present in 12 moles of ch₄?
○ 48 moles h
○ 4 moles h
○ 12 moles h
○ 3 moles h

Explanation:

Step1: Analyze the formula of \( CH_4 \)

In one molecule of \( CH_4 \) (methane), there are 4 atoms of hydrogen (H). So, in terms of moles, 1 mole of \( CH_4 \) contains 4 moles of H.

Step2: Calculate moles of H in 12 moles of \( CH_4 \)

If 1 mole of \( CH_4 \) has 4 moles of H, then 12 moles of \( CH_4 \) will have \( 12 \times 4 = 48 \) moles of H.

Answer:

48 moles H
