Answer to Question #208222 in Chemistry for Kida

Question

what mass of CH4 formed when 8.3 moles of CO react with        hydrogen according to following equation?

2CO  +  2H2  → CH4 + CO2

Answer 1

Solution:

Balanced chemical equation:

2CO + 2H₂ → CH₄ + CO₂

According to the equation above: n(CO)/2 = n(CH₄)

n(CH₄) = n(CO) / 2 = 8.3 mol / 2 = 4.15 mol

The molar mass of CH₄ is 16.04 g/mol.

Therefore,

(4.15 mol CH₄) × (16.04 g CH₄ / 1 mol CH₄) = 66.566 g CH₄ = 66.6 g CH₄

Answer: 66.6 grams of CH₄ formed.
