$16{\mathrm{CaOCl}}_2+4{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\to 7{\mathrm{CaCl}}_2+8\mathrm{Ca}(\mathrm{OH}{)}_2+6{\mathrm{CHCl}}_3+\mathrm{Ca}(\mathrm{HCOO}{)}_2$

CHCl₃ + O₂ → COCl₂ + HCl

2.216 gm mixture of bleaching powder and ethanol, whose $91.7\%$ (by $\mathrm{W}/\mathrm{W}$ ) is ${\mathrm{CaOCl}}_2$, completely reacts with each other. Resulting ${\mathrm{CHCl}}_3$ formed, when react with air produces ${\mathrm{COCl}}_2$ (phosgene) gas. Mass of ${\mathrm{COCl}}_2$ produced is ' $\mathrm{M}(\mathrm{mg})$ '. Find $\mathrm{M}/99$.

(Atomic Mass : Ca = 40 u, Cl = 35.5 u, O = 16 u, C = 12 u, H = 1 u)
