Question

The amount of energy required to convert 70mg of lithium atoms in gaseous state inti li+ ions

Answer 1

$\rule{200}{2}$

$\huge\boxed{\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R:-}}}}}$

molar mass of li=6

70 mg of li= 70*1/1000=0.7g

therefore

0.7*1/6=0.1

Li+= 520 kj/mol

li= 0.1* 520=5.2 kj

Answer 2

Answer:

molar mass of li=6

70 mg of li= 70*1/1000=0.7g

therefore

0.7*1/6=0.1

Li+= 520 kj/mol

li= 0.1* 520=5.2 kj
