Explanation:

Answer 2

$\Huge\underline{\underline{\mathfrak \orange{Answer}}}$

Mass decay per hour is ${\bf \blue{43.9×10^{-6}g}}$ .

$\Huge\underline{\underline{\mathfrak \orange{Solution}}}$

$\large\underline{\underline{\sf Given:}}$

• Power obtained in a reactor using $\sf{U^{235}}$ = 1000kW

$\large\underline{\underline{\sf To\:Find:}}$

• Mass decay of $\sf{U^{235}}$ per hour is

Let assume ,

Power = 1000 W

Energy per hour = 1000 × 3600 J

Energy per fission = 1000 × 3600 J

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 200 × 1.6 ×$\sf{10^{-13}}$ J

✮ Number of fission per hour

$\implies{\sf n=\dfrac{1000×3600}{200×1.6×10^{-13}J}}$

✮ Number of moles per hour

$\large{\boxed{\sf \green{Numbers\:of\:mole\:per\:hour=\dfrac{n}{N} }}}$

✮ Mass per hour

$\large{\boxed{\boxed{\sf \green{Mass\:per\:hour=\dfrac{n}{N}×225}}}}$

$\implies{\sf \dfrac{1000×3600×235}{200×1.6×10^{-13}×6.02×10^{23} }}$

$\implies{\sf 43.9×10^{-6}g }$

⛬ Mass decay per hour is ${\bf \blue{43.9×10^{-6}g}}$ .
