Answer 1

$\huge\underline{\overline{\mid{\bold{\orange{ANSWER-}}\mid}}}$

⭐Given-

• Charge=  50 × 10⁻⁹

• Charge on one electrons= 1.6 × 10⁻¹⁹

⭐Find-

• no. of electrons transferred??

⭐Formula-

• $\boxed{Q=\pm ne}$

⭐Solution-

• Putting value in formula,

• 50 × 10⁻⁹ = n × 1.6 × 10⁻¹⁹

• n = 31.25 × 10¹⁰

Answer 2

AnSwEr :

${\red\bigstar\Large\bold{\underline{\textsf{\green{Given:}}}}}$

• Charge (Q) = 50nc = $\sf 50 \times {10}^{-9} C$

• An electron carries charge = $\sf 1.6 \times {10}^{-19}$

${\red\bigstar\Large\bold{\underline{\textsf{\green{To\:Find:}}}}}$

• Number of electrons transferred

${\red\bigstar\Large\bold{\underline{\textsf{\green{Solution:}}}}}$

✴ FORMULA USED : $\large\bold{\boxed{\sf{\pink{Q\:=\:±ne}}}}$

★ $\sf 50 \times {10}^{-9} C \:=\: n \times 1.6 \times {10}^{-19}$

★ $\sf n\:=\: \dfrac{50 \times {10}^{-9} C}{1.6 \times {10}^{-19}}$

${\orange\bigstar\Large\bold{\underline{\sf{\red{n\:=\:31.25 \times{10}^{10}}}}}}$
