6.022 x 1023 ions= 1mol

They both have the same amount of particles; have in common?

6.022 x 1023 particles

No, according to the periodic table, each substance has a different mass. They just are the same number of particles.

What’s the molar mass of chlorine? different mass. They just are the same number of particles.

35.45g/mol different mass. They just are the same number of particles.

1 mol Cl factor.35.45g Cl

35.45g Cl or 1 mol Cl

If a test question asked you to calculate average atomic mass what numerical data would have to be given in the problem?

The mass of the isotopes and the mass what numerical data would have to be given in the problem?% abundance.

The empirical formula is the simplified ratio and the molecular formula is how the molecule actually exists.

How many significant figures does 700.10 have in it? molecular formula is how the molecule actually exists.

5 molecular formula is how the molecule actually exists.

Round 367.895 to the hundredths place. molecular formula is how the molecule actually exists.

367.90 molecular formula is how the molecule actually exists.

Molecular mass molecular formula?empirical mass

Divide by small molecular formula?

How can you check your answer in a percent composition problem to make sure there are no obvious errors?

Make sure the percents add up to 100%. problem to make sure there are no obvious errors?

Particles, ions, atoms, molecules, and formula units. given in the problem.

That means whenever you write 6.022 x 1023 you must have one of those units behind it.

NOT g or mol.

Tell whether the following is an atom or molecule. given in the problem.

CO2

H2O

Al

H2

CO given in the problem.2 molecule

H2O molecule

Al atom

H2 molecule

How many conversions would you use if the given in the problem.given was atoms and the find was grams?

2 given in the problem.

40.08amu given in the problem.
