0.22moles

Explanation:

Given parameters:

Volume of gas = 4.92L

Unknown:

Number of moles  = ?

Condition = STP

Solution

At STP, the number of moles of a given gas is expressed as;

     Number of moles  = [tex]\frac{volume given}{22.4}[/tex]  

 Number of moles  = [tex]\frac{4.92}{22.4}[/tex]   = 0.22moles
