Question

[
B a C O_{3} Rightarrow B a O+C D_{2}
]
1 mote of ( mathrm{E}_{0} mathrm{LO}_{3} ) glives 1 mole of ( mathrm{co}_{2} ). So, 197 gmol Balos gives ( 44 mathrm{gm} ) of ( mathrm{cD}_{2} )
[
=2.2 mathrm{gm}: 100_{2}
]
No. of moter of ( w_{2}=frac{2.2}{44}=0.05 ) moles
&o, 1 mole of ( cos 2 ) at st p occupres ( 2.2 .4 mathrm{l} ). How oros mole of ( 60, ) at stipunu ber
[
begin{array}{l}
=22.4 times 0.05
=1.12 mathrm{l}
end{array}
