\(=\frac{12}{44} \times \frac{\text { mass of } CO _2 \text { formed }}{\text { mass of compound taken }} \times 100\)
\(60=\frac{12}{44} \times \frac{\text { mass of } CO _2 \text { formed }}{0.5} \times 100\)
Mass of \(CO _2\) formed \(=\frac{60 \times 44 \times 0.5}{12 \times 100}\,g\)
\(=1.1 \text { gram }\)
\(=11 \times 10^{-1} \text { gram }\)
