1 mole of CH1 contains
Correct answer: A. 6.02 x 10^23 atoms of H
- A. 6.02 x 10^23 atoms of H
- B. 4 g-atom of hydrogen
- C. 1.81 x 10^2 molecules of CH
- D. 3.0 g of carbon
Explanation
The chemical formula CH1 represents one mole of methane. Methane (CH4) is composed of one carbon atom (C) and four hydrogen atoms (H).1 mole of CH1 contains:● 1 mole of C atoms● 4 moles of H atomsAvogadro's number (6.02×10236.02×1023) is the number of entities (atoms, molecules, etc.) in one mole of a substance. Therefore, for hydrogen (H), which is a diatomic molecule (H2), 1 mole of hydrogen contains 6.02×10236.02×1023 atoms.So, for the given molecule CH1:● 1 mole of C contains 6.02×1023 atoms of C.● 4 moles of H contain 4×6.02×1023=24.08×1023 atoms of H.The correct answer is option a. 6.02×1023 atoms of H.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
