Chemistry - Mole Concept Question with Solution | TestHub

Isobutane and n-butane$\left[{\mathrm{C}}_4{\mathrm{H}}_{10}\right]$have same molecular formula;${\mathrm{C}}_4{\mathrm{H}}_{10}+\frac{13}{2}{\mathrm{O}}_2\to 4\mathrm{C}{\mathrm{O}}_2+5{\mathrm{H}}_2\mathrm{O}$
For 58gm of${\mathrm{C}}_4{\mathrm{H}}_{10}$208 gm${\mathrm{O}}_2$is required then for 5 kg of${\mathrm{C}}_4{\mathrm{H}}_{10}$${\mathrm{O}}_2=\frac{5\times 208}{58}=17.9\mathrm{}\mathrm{}\mathrm{ k}\mathrm{g}$
