The answer to your first question is yes....
Explanation:
As to the answer, we write the stoichiometric equation to inform our arithmetic.....
This is a redox equation for which BOTH charge and mass are balanced....
And so we find the moles of sodium metal....
And given the stoichiometry of the reaction (what do I mean by this?), there is half an equiv of dioxygen gas....i.e. a mass of....
And thus we get mass of approx.
