Q
Q: What is the mass of 2 moles of carbon dioxide (CO2)?
Solution:
The molar mass of CO2 is 12 g/mol (C) + 16 g/mol x 2 (O) = 44 g/mol. Therefore, 2 moles of CO2 weigh 2 x 44 g = 88 g.
Steps: 6
Show Steps
Step 1: Identify the chemical formula of carbon dioxide, which is CO2.
Step 2: Find the molar mass of carbon (C), which is 12 g/mol.
Step 3: Find the molar mass of oxygen (O), which is 16 g/mol.
Step 4: Since there are 2 oxygen atoms in CO2, calculate the total mass of oxygen: 16 g/mol x 2 = 32 g/mol.
Step 5: Add the mass of carbon and the total mass of oxygen to find the molar mass of CO2: 12 g/mol + 32 g/mol = 44 g/mol.
Step 6: To find the mass of 2 moles of CO2, multiply the molar mass by the number of moles: 2 moles x 44 g/mol = 88 g.
