The atomic weight of Li is 6.941 g/mol
The mass of the sample is 55.2 g
This means that:
55.2/6.941=7.95 moles (rounded number)
Multiplying this with Avogadro's number (6.022*1023)
7.95*6.022*1023=4.79*1024 atoms.
There you have your answer.

How many LI atoms are contained in 97.9 of LI?
I assume you mean 97.9 grams lithium. 97.9 grams lithium (1 mole Li/6.941 grams)(6.022 X 10^23/1 mole Li) = 8.49 X 10^24 atoms of lithium ---------------------------------------
How many atoms are in 12.7grams of lithium?
12.7 grams lithium (1 mole Li/6.941 grams)(6.022 X 10^23/1 mole Li) = 1.10 X 10^24 atoms of lithium
How many lithium atoms are present in 0.01456 of lithium?
I assume you mean; 0.01456 grams lithium (1 mole Li/6.941 grams)(6.022 X 10^23/1 mole Li) = 1.263 X 10^21 atoms of lithium
How many atoms are in 3.00 moles of Li?
3,00 moles of Li have 18,066422571.10e23 atoms.
How many atoms in Li?
Lithium hydroxide has three atoms in it, one each of lithium, hydrogen, and oxygen. Also note that lithium is Li, not LI. Little details matter to chemists. A capital I means iodine.
What is the mass in grams of 2.56 x 10.24 atoms Li?
2.59 atoms?? Oh well. 2.59 atoms Li (1mol Li/6.022 X 10^23 )(6.941 grams Li/1mol Li ) = 2.98 X 10^-23 grams
