Answer

3.0 L Explanation 1. Identify the reaction Assume a balanced chemical equation involving X, Y, and Z. For example, X + Y \rightarrow Z. 2. Use STP conditions At STP (Standard Temperature and Pressure), 1 mole of gas occupies 22.4 L. 3. Calculate moles from volume Initial volume is 3.0 L. Moles of reactants = \frac{3.0 \text{ L}}{22.4 \text{ L/mol}}. 4. Determine moles of Z produced Assuming complete reaction, moles of Z = moles of reactants. 5. Calculate volume of Z Volume of Z = moles of Z \times 22.4 L/mol.

Explanation

1. Identify the reaction<br /> Assume a balanced chemical equation involving X, Y, and Z. For example, $X + Y \rightarrow Z$.<br /><br />2. Use STP conditions<br /> At STP (Standard Temperature and Pressure), 1 mole of gas occupies 22.4 L.<br /><br />3. Calculate moles from volume<br /> Initial volume is 3.0 L. Moles of reactants = $\frac{3.0 \text{ L}}{22.4 \text{ L/mol}}$.<br /><br />4. Determine moles of Z produced<br /> Assuming complete reaction, moles of Z = moles of reactants.<br /><br />5. Calculate volume of Z<br /> Volume of Z = moles of Z $\times$ 22.4 L/mol.
