Match the question with the correct conversion factor needed.

Column A
1.What is the mass, in grams, of a single atom of carbon?:
2.What is the mass, in grams, of a single atom of iron?:
3.What is the mass, in grams, of a single molecule of water?:
4.What is the mass, in grams, of a single molecule of CO2?:

Column B
a. (12.01 g/6.02E23 atoms)
b. (44.01 g/6.02E23 molecules)
c. (55.85 g/6.02E23 atoms)
d. (18.01 g/6.02E23 molecules)

what is the atomic mass of C?

what is the atomic mass of Fe
What is the molecular mass of CO2?
What is the molecular mass of H2O?

1. What is the mass, in grams, of a single atom of carbon?: Column B - a. (12.01 g/6.02E23 atoms)

2. What is the mass, in grams, of a single atom of iron?: Column B - c. (55.85 g/6.02E23 atoms)
3. What is the mass, in grams, of a single molecule of water?: Column B - d. (18.01 g/6.02E23 molecules)
4. What is the mass, in grams, of a single molecule of CO2?: Column B - b. (44.01 g/6.02E23 molecules)

To determine the correct conversion factor, you need to consider the molar mass of the substance and Avogadro's number. The molar mass represents the mass of one mole of a substance, expressed in grams. Avogadro's number (6.02E23) represents the number of atoms or molecules in one mole of a substance.

For example, to find the mass of a single atom of carbon (question 1), you need to use the molar mass of carbon (12.01 g/mol) and divide it by Avogadro's number (6.02E23 atoms/mol). This gives you the conversion factor of 12.01 g/6.02E23 atoms.

By matching the questions in Column A with the correct conversion factors in Column B, you can find the mass of the requested particles in grams.
