To solve the problem, we need to determine the volume of carbon dioxide (CO₂) produced from the thermal decomposition of 20 grams of potassium bicarbonate (KHCO₃) at standard temperature and pressure (STP). Here are the step-by-step calculations: ### Step 1: Calculate the molar mass of KHCO₃ The molar mass of KHCO₃ can be calculated as follows: - Potassium (K) = 39 g/mol - Hydrogen (H) = 1 g/mol - Carbon (C) = 12 g/mol - Oxygen (O) = 16 g/mol (there are 3 oxygen atoms) ...
