The amount of

\mathrm{BaSO}_4

formed upon mixing 100

\mathrm{mL}

of

20.8 \% \mathrm{BaCl}_2

solution with

50 \mathrm{~mL}

of

9.8 \%

\mathrm{H}_2 \mathrm{SO}_4

solution will be:

(\mathrm{Ba}=137, \mathrm{Cl}=35.5, \mathrm{~S}=32, \mathrm{H}=1

and

\mathrm{O}=16

)

Options

A $23.3 \mathrm{~g}$
B $11.65 \mathrm{~g}$
C $30.6 \mathrm{~g}$
D $33.2 \mathrm{~g}$

Correct answer

A. $23.3 \mathrm{~g}$

Step-by-step solution

\mathrm{BaCl}_2+\mathrm{H}_2 \mathrm{SO}_4 \longrightarrow \mathrm{BaSO}_4+2 \mathrm{HCl}

\begin{array}{llll}208 \mathrm{~g} & 98 \mathrm{~g} & 233 \mathrm{~g} & 73 \mathrm{~g} \\ 20.8 \mathrm{~g} & 9.8 \mathrm{~g} & 23.3 \mathrm{~g} & 7.3 \mathrm{~g}\end{array}
