A metal surface of

100 \mathrm{~cm}^{2}

area has to be coated with nickel layer of thickness

0.001 \mathrm{~mm}

. A current of

2 \mathrm{~A}

was passed through a solution of

\mathrm{Ni}\left(\mathrm{NO}_{3}\right)_{2}

for '

\mathrm{x}

' seconds to coat the desired layer. The value of

\mathrm{x}

is __________. (Nearest integer) (

\rho_{\mathrm{Ni}}

(density of Nickel) is

10 \mathrm{~g} \mathrm{~mL}
