determine the mass of butane that burned when 2.46g water were produced​

Answer 1

Complete combustion of Hydrocarbons with Oxygen will produce CO₂ and H₂O

Combustion of butane (C₄H₁₀) :

`\tt 2C_4H_(10)+26O_2\rightarrow 8CO_2+10H_2O`

2.46 g water(H₂O) were produced​

• mol of water

`\tt (2.46)/(18)=0.137`

• mol of butane

`\tt (2)/(10)* 0.137=0.0274`

• mass of butane

MW : 58,12 g/mol

`\tt mass=mol* MW\\\\mass=0.0274* 58.12\\\\mass=\boxed{\bold{1.592~g}}`
