From the reaction \mathrm{1 \mathrm{~mol}} of toluene is converted into \mathrm{1 \mathrm{~mol}} of benzaldehyde but yield is  \mathrm{92 \%}  so \mathrm{\0.92\, mol} of benzaldehyde form.

\mathrm{1\: mole \: \mathrm{Ph}-\mathrm{CH}_{3} \longrightarrow 0.92\: mole \: \mathrm{Ph}-\mathrm{CHO}}
\mathrm{92 \: gram \: \mathrm{Ph}{-\mathrm{CH}_{3}} \longrightarrow 0.92 \mathrm{~mol} \: \mathrm{Ph}-\mathrm{CHO}}
\mathrm{5 \: gram \: \mathrm{Ph}{-\mathrm{CH}_{3}} \longrightarrow 0.05 \mathrm{~mol} \: \mathrm{Ph}-\mathrm{CHO}}
\mathrm{5 \: gram \: \mathrm{Ph}{-\mathrm{CH}_{3}} \longrightarrow 5.30 \mathrm{~gram} \: \mathrm{Ph}-\mathrm{CHO}}

\mathrm{Amount \, of \, benzaldehyde =530 \times 10^{-2} \mathrm{~g}.}
Ans = 530.
