Question

(1) 5.6 lit 7 He ( therefore 22 cdot 410 t=1 mathrm{m} cdot mathrm{l} )
( 5.6 mathrm{li} mathrm{r}=frac{5.6}{22.4} mathrm{mol} . Rightarrow frac{1}{4}=0.25 mathrm{mol} )
"N. ( 11 mathrm{gm} ) of ( mathrm{cor} ) ( Rightarrow 44 g m=1 m o u )
( operatorname{lig}_{m}=frac{1}{44} x |=0.25 mathrm{mol} )
(ii) ( 9 operatorname{gm} x+120 )
( 3.12 mathrm{gm} mathrm{H}_{2} mathrm{O}=1 mathrm{mol} )
( g g_{m}-=frac{1}{18} x g=0.5 mathrm{mol} )
( v_{9 m} mathrm{H}_{20}+1 operatorname{lgm}left(mathrm{s}_{2}right. )
( Rightarrow frac{9}{18} mathrm{mol} mathrm{H}_{2} mathrm{s}+frac{11}{44} mathrm{mi} mathrm{cus} )
( 5+0.25=0.75 mathrm{m} d mathrm{s} )
