To solve the problem of finding the volume of ammonia gas at Standard Temperature and Pressure (S.T.P) given the number of molecules, we can follow these steps: ### Step 1: Identify the number of molecules We are given that the number of molecules of \( NH_3 \) is \( 7.2 \times 10^{20} \). ### Step 2: Calculate the number of moles To find the number of moles, we use Avogadro's number, which is \( 6 \times 10^{23} \) molecules/mol. The formula to convert molecules to moles is: ...
