AI Generated Solution

To solve the question "At S.T.P., 22.4 L of a gas contain ........... molecules," we will follow these steps: ### Step 1: Understand the concept of STP STP stands for Standard Temperature and Pressure, which is defined as a temperature of 0 degrees Celsius (273.15 K) and a pressure of 1 atmosphere (atm). Under these conditions, 1 mole of an ideal gas occupies 22.4 liters. ### Step 2: Identify the volume of gas The volume of the gas given in the question is 22.4 liters. ...
