Well, what is the mass of ONE MOLE of sodium metal?

My Periodic Table tells me that it has a mass of $22.99*g*mol^-1$ .

And for the mass associated with $4.30*mol$ of sodium...we take the product...

$4.30*molxx22.99*g*mol^-1~=99*g.$

The mass of $"4.30 mol Na"$ is $"98.9 g"$ .

Multiply the given moles of sodium by its molar mass $("22.990 g/mol")$ .

$4.30color(red)cancel(color(black)("mol Na"))xx(22.990"g Na")/(1color(red)cancel(color(black)("mol Na")))="98.9 g Na"$
