Mass of CH₄ is 10.591 g.
The molar mass is a crucial characteristic of the material that is independent of sample size. The coherent unit of molar mass in the International System of Units (SI) is kg/mol. However, molar masses are usually generally given in g/mol due to historical considerations.
A chemical compound's molar mass is calculated by dividing its mass by the number of moles of the substance that make up the sample.
Δg = 587.9 KJ
CH₄ Molar mass = 16.05 g/mol
mol CH₄ = Δg / ΔH°
= 587.9 / 890.3 KJ/ mol
= 0.6603 mol CH₄
Mass CH₄ = 0.6603 × 16.05 g/mol
= 10.591 g
Therefore, the mass of CH₄ is 10.591 g.

Answer:
B. Better ways to recycle plastics
Explanation:
A chemist might choose to study better ways to recycle plastics because there may be certain types of chemicals that can disintegrate the plastic..
That's actually a polyatomic Ion, so it's an Ionic bond, because Aluminum is a metal, and sulfate is a covalent compound.
Answer:
Explanation:
3NO₂ + H₂O → 2HNO₃ + NO
n/mol: 12.66
You get 1 mol of NO from 3 mol of NO₂
