The ratio of the volumes between equal masses of O2, H2 and CH4 is:
Correct answer: B. 1:16:2
- A. 1 :1 :1
- B. 1:16:2
- C. 2:16:2
- D. 2:16:1
Explanation
Moles of O2 =1/32= 0.03125 Moles of H2= 1/2=0.5 Moles of CH4= 1/16=0.0625 Use ideal gas law to find volumes. PV=nRT. Volume ratios: VO2/VH2 = 0.03125/0.5=0.0625 VO2/VCH4=0.03125/0.0625=0.5 VH2/VCH4=0.5/0.0625=8 So the simplified ratio of O2,H2 and CH4 is 1:16:2 respectively. So option B is the correct answer.

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.
