Answer is: 1 mol CH ₄ / 16,0 g CH ₄.

Chemical reaction: CH₄ + 2O₂ → CO₂ + 2H₂O.

m (CH₄) = 50,6g.

M (CH₄) = 16g/mol.

n (CH₄) = m (CH₄) : M (CH₄) = 50,6g : 16g/mol = 3,16mol.

n (CH₄) : n (CO₂) = 1:1.

nCO₂) = 3,16mol.

m (CO₂) = m (CO₂) · m (CO₂) = 3,16mol · 44g/mol = 139,15g.

M - molar mass.

n - amount of substance.
