$\sf \red {\underline{\underline{Provided\: that:}}}$

➻Weight of methane =1.5grams.

$\sf \blue {\underline{\underline{To\: determine:}}}$

➻Weight of carbon dioxide formed by the complete combustion of methane.

━═━═━═━═━═━═━═━═━═━

$\sf \pink {\underline{\underline{Balanced\: chemical\: Equation:}}}$

$\sf {CH_{4}+2O_{2}\longrightarrow CO_{2}+2H_{2}O}$

━═━═━═━═━═━═━═━═━═━

$\sf \purple {\underline{\underline{We\: know:}}}$

$\tt {\boxed{Mass\: of\: CH_{4}}}$

$\to \sf {12+4×1}$

$\to \sf {12+4}$

$\implies \sf \green {Mass\: of\: CH_{4}=16grams}$

━═━═━═━═━═━═━═━═━═━

$\tt {\boxed{Mass\: of\: CO_{2}}}$

$\to \sf {12+2×16}$

$\to \sf {12+32}$

$\implies \sf \green {Mass\: of\: CO_{2}=44grams}$

➻If , 16 grams of methane produces 44 grams of carbon dioxide,

➻1.5 grams of will produce ____? grams of carbon dioxide

$\large \to \sf {\frac{44}{16}×1.5}$

$\large \to \sf {\frac{66}{16}}$

$\implies \sf \green {\boxed{\underline{4.125(Apx)}}}$

$\sf \orange {\underline{\underline{Therefore,}}}$

➻Weight of carbon dioxide formed by the complete combustion of 1.5 grams of methane is 4.125 grams respectively.
