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"#
