question one suppose that the KMnO$4($aq$)$

were standardized by reaction with As$2$O$3$

$.$

As$2$O$3+$MnO$4+$H$++$H$2$O$->$H$3$AsO$4+$Mn$2+$

$($not balanced$).$ If a $0\mathrm{.}1330-$ g

sample that is $99\mathrm{.}36\%$

As$2$O$3$

by mass had been used in the titration, how many milliliters of the $0\mathrm{.}02140$ M

KMnO$4($aq$)$

would have been required?

Express your answer using four significant figures. question $2.$ The reaction below can be used as a laboratory method of preparing small quantities of Cl$2($g$)$

$.$

Cr$2$O$27+$H$++$Cl$->$Cr$3++$H$2$O$+$Cl$2($g$)$

$($not balanced$).$ If a $33\mathrm{.}8-$ g

sample that is $98\mathrm{.}5\%$

K$2$Cr$2$O$7$

by mass is allowed to react with $325$ mL

of HCl$($aq$)$

with a density of $1\mathrm{.}15$ g$/$mL

and $30\mathrm{.}1\%$ HCl by mass, how many grams of Cl$2($g$)$

are produced?. you have to find mCl$2?$ note. these are the parts of same question. dont consider them $2.$ and be sure while writing the answer........
