27.9L

Explanation:

Given parameters:

Number of molecules = 7.5 x 10²⁴molecules

Condition = STP

Unknown:

Volume of gas = ?

Solution;

The volume of gas at STP is expressed below;

 Volume of gas = number of moles x 22.4

Number of moles = \frac{Number of molecules }{6.02 x 10^{23} }

    Now if we can obtain the value of the number of moles from the expression above, we can plug it back into the equation of the volume of gas at STP;

     Number of moles of NH₃ =  \frac{[tex]7.5 x 10^{24} }{6.02 x 10^{23} }[/tex]

   Number of moles of NH₃ = 12.5moles

Volume of gas = 12.5 x 22.4 = 27.9L
