MCQ
Which has the maximum number of molecules among the following?
- A$44\; g\ CO_2$
- B$48\; g\ O_3$
- ✓$8\; g\ H_2$
- D$64\; g\ SO_2$
$64 g$ $SO_2=1$ mole
$44 \mathrm{g} \mathrm{CO}_2=1 \mathrm{mole}$
$48 \mathrm{g} O_2=48 / 32=1.5 \mathrm{mole}$

${C_{(gr)}} + {O_{2(g)}} \to C{O_{2(g)}}\,\,\,\Delta H = x\,kJ/mol$
${C_{(gr)}} + \frac{1}{2}{O_{2(g)}} \to C{O_{(g)}}\,\,\,\Delta H = y\,kJ/mol$
$C{O_{(g)}} + \frac{1}{2}{O_{2(g)}} \to C{O_2}_{(g)}\,\,\,\Delta H = z\,kJ/mol$
