\(CO_2\) નું દળ \(= 10\) ગ્રામ

મળતા \(CaO\)  નું દળ \(= x\)

દળ સંરક્ષણ નિયમ અનુસાર

\(\begin{array}{l}
10\,\,\, = \,\,\,\,4.4 + x\,\,\,\, \Rightarrow \,\,\,\,10 - 4.4\,\,\,\, = \,\,\,\,x\,\,\,\, \Rightarrow \,\,\,x\,\,\, = \,\,\,5.6g\\
\,\,1\,\,{\rm{quintal}}\,\, = \,\,\,\,{\rm{100kg}}\\
\therefore \,\,{\rm{1}}\,\,{\rm{Kg}}\,\,\,\, = \,\,\,\,{\rm{1000g}}\\
\, = \,\,\,\,{\rm{5}}{\rm{.6}}\,{\rm{g}}\, \times \frac{{{\rm{Kg}}}}{{{\rm{1000}}}}\,\,\,\, = \,\,5.6\,\, \times \,\,{10^{ - 3}} \times \frac{1}{{100}}{\rm{quintal}}\,\,\, = \,\,\,\,{\rm{5}}{\rm{.6}} \times {\rm{1}}{{\rm{0}}^{{\rm{ - 5}}}}\,{\rm{quintal}}
