Questions & Step-by-Step Solutions
What is the number of moles in 44 grams of carbon dioxide (CO2)? (2023)
Step 1: Understand that a mole is a unit that measures the amount of a substance.
Step 2: Find the molar mass of carbon dioxide (CO2).
Step 3: Calculate the molar mass of CO2: Carbon (C) has a mass of about 12 g/mol and Oxygen (O) has a mass of about 16 g/mol. CO2 has 1 Carbon and 2 Oxygens, so: 12 g/mol + (2 * 16 g/mol) = 44 g/mol.
Step 4: Use the formula: Number of moles = mass (g) / molar mass (g/mol).
Step 5: Plug in the values: Number of moles = 44 g / 44 g/mol.
Step 6: Calculate: 44 g / 44 g/mol = 1 mole.
