What weight of sodium hydroxide will react with 73 gram of hydrogen chloride gas at NTP to Produce 117.0 gram of Nacl and 36 gra

Wewaii [24]

Let's write the equation

$\\ \sf\longmapsto {NaOH\atop ?}+{HCl\atop 73g}\longrightarrow {NaCl\atop 117g}+{H_2O\atop 36g}$

According to law of conservation of mass .

Mass of products=Mass of reactants

Let required value be x

$\\ \sf\longmapsto x+73=117+36$

$\\ \sf\longmapsto x+73=153$

$\\ \sf\longmapsto x=153-73$

$\\ \sf\longmapsto x=80g$

Letter A has primary and secondary alcohol so I discard this choice.

Letter B has secondary alcohol, so this is the correct choice.

The letter C has a primary and 2 secondary alcohols so I discard this choice.
