Answer:

140g/mol

The mass of silicon is expressed according to the formula:

$Mass\text{ of Silicon}=moles* molar\text{ mass}$

Given the following parameters

• Moles of silicon = 5.0moles

,

• Molar mass of silicon = 28g/mol

Substitute the given parameters into the formula

$\begin{gathered} Mass\text{ of silicon}=5.0moles*(28g)/(mol) \\ Mass\text{ of silicon}=140g\text{/}mol \end{gathered}$

Hence the mass of silicon is 140g/mol
