What is the mass in milligrams of 4.30 moles of sodium? use âeâ for âã10" and use significant figures?

First, calculate the mass of sodium in g with the help of molar mass and number of moles.

Number of moles =   (1)

Molar mass of sodium =

Substitute the given value of number of moles and molar mass of sodium in formula (1)

  (1)

  (1)

mass of sodium in g =

Now, according to conversion factor, 1 g = 1000 mg

So, of sodium =

= of sodium

Thus, mass of sodium in mg  =
