Question

caculate the number of moles in 50g of Na

Answer 1

Hey mate!

_______________________

Given Mass = 50g.

Molar mass = 22.98 g.

We know that ;

To find the number of moles, we divide Given Mass by the molar mass.


No of moles = Given Mass / molar mass.

No of moles = 50 / 22.98

No of moles = 2.17 moles.

Answer 2

Molar mass of Sodium (Na)= 22.98g

Given Mass = 50 g

Number of moles =
$\frac{given \: mass}{molar \: mass} \\ = \frac{50}{22.8} = 2.17moles \:$

The number of moles required is = 2.17 moles .
