Question

Answer 1

Answer:

hahaha kya hai mujhe koi matlab nhi

Answer 2

• Molar mass of Na=23g/mol
• Given mass=4.6g

We know

$\boxed{\sf No\:of\:moles=\dfrac{Given\:Mass}{Molar\:mass}}$

$\\ \sf\longmapsto No\:of\:moles=\dfrac{4.6g}{g/mol}$

$\\ \sf\longmapsto No\:of\;moles=0.2mol$

There are 0.2moles of Na present in 4.6g
