Question: How many grams are in 2 moles of carbon dioxide (CO2)?

Options:

Correct Answer: 88 g

Solution:

The molar mass of CO2 is 44 g/mol. Thus, 2 moles of CO2 = 2 x 44 g = 88 g.

How many grams are in 2 moles of carbon dioxide (CO2)?

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). This is the mass of one mole of CO2.
Step 3: Calculate the molar mass of CO2 by adding the atomic masses of its elements: Carbon (C) = 12 g/mol and Oxygen (O) = 16 g/mol.
Step 4: CO2 has 1 Carbon and 2 Oxygens, so the calculation is: 12 g/mol (C) + 2 * 16 g/mol (O) = 12 + 32 = 44 g/mol.
Step 5: Now, to find the mass of 2 moles of CO2, multiply the molar mass by the number of moles: 2 moles * 44 g/mol.
Step 6: Perform the multiplication: 2 * 44 = 88 grams.
Step 7: Conclude that there are 88 grams in 2 moles of carbon dioxide (CO2).
