The equivalent energy of 1 g of substance is.

$9 \times 10^{13}J$

$6 \times 10^{12}J$

$3 \times 10^{13}$ J

$6 \times 10^{13}J$

Answer

$9 \times 10^{13}J$

Explanation

: using, $E = mc^{2}$

Here, $m = 1g = 1 \times 10^{- 3}kg$

$c = 3 \times 10^{8}ms^{- 1}$

$\therefore E = 10^{- 3} \times 9 \times 10^{16} = 9 \times 10^{13}j$
