184g
The formula for calculating the mass of a substance is expressed as;
[tex]moles=mass\times molar\text{ mass}[/tex]Given the following parameters
• Moles of Na = 8moles
,• Molar mass of Na = 23g/mol
Substitute the given parameter into the formula
[tex]\begin{gathered} Mass\text{ of Na}=moles\times molar\text{ mass} \\ Mass\text{ }of\text{ Na}=8moles\times\frac{23g}{mol} \\ Mass\text{ of Na}=184g \end{gathered}[/tex]Hence the mass of the sodium is 184g
