Web3 jul. 2024 · One mole of a compound contains 6.022x10 23 molecules of the compound. The mass of one mole of a compound is called its molar weight or molar mass. The units for molar weight or molar mass are grams per mole. Here is the formula for determining the number of moles of a sample: mol = weight of sample (g) / molar weight (g/mol) 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 …
