Web3 jun. 2024 · 0.68 moles C3H8 * 3 moles CO2/1 mole C3H8 = 2.04 moles CO2. Now that we found moles of CO2 produced from 30.0 g C3H8, we want to use that same process using 75.0 g oxygen. We start with 75.0 g oxygen and we can determine that the molar mass of oxygen is 32.0 grams, which again we can use to convert between grams and … WebSolution. Step 1: Convert all masses into moles. 1.20g Al × 1 mol Al 26.98g Al = 0.044 48 mol Al. 2.40g I₂ × 1 mol I2 253.8g I₂ = 0.009 456 mol I2. Step 2: Calculate the molar ratios. To calculate the molar ratios, you put the moles …
