Title: Calculating Gas Volume at Standard Temperature and Pressure (STP)---**Chemical Reaction and Gas Production**In a chemical reaction, gas is produced as a result of the interaction described by the following equation:\[ \text{Zn(s)} + 2 \text{HCl(aq)} \rightarrow \text{ZnCl}_2 + \text{H}_2(g) \]**Problem Statement**You have determined that 2.695 moles of \( \text{H}_2(g) \) were produced in this reaction.**Question**At standard temperature and pressure (STP), what volume in liters of \( \text{H}_2 \) will be produced?**Important Information**- The gas constant, \( R \), is 0.08206 L·atm/mol·K.- Standard Temperature and Pressure (STP) is defined as 0°C (273.15 K) and 1 atm pressure.**Approach to Solution**To find the volume of hydrogen gas at STP, use the ideal gas law equation:\[ PV = nRT \]Where:- \( P \) is the pressure (1 atm at STP)- \( V \) is the volume in liters- \( n \) is the number of moles (2.695 moles)- \( R \) is the gas constant (0.08206 L·atm/mol·K)- \( T \) is the temperature in Kelvin (273.15 K at STP)Rearranging the formula to solve for volume:\[ V = \frac{nRT}{P} \]Substituting the known values:\[ V = \frac{2.695 \times 0.08206 \times 273.15}{1} \]Calculate this to find the volume of \( \text{H}_2 \) produced. ---

A gas is formed in the reaction shown below. The gas laws can help determine the volume of gas produced. Zn(s) + 2 HCl(aq) → ZnCl, + H2(g) You have determined that 2.695 moles of H2(g) were produced in this reaction. At STP, what volume in L of H, will be produced? Remember the gas constant, R, is 0.08206 L·atm/mol·K.
