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.

To find the number of atoms in 55.2 grams of lithium (Li), you need to first determine the molar mass of lithium, which is approximately 6.94 g/mol. Then, use this value to convert the grams of lithium to moles. Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of atoms in 55.2 grams of lithium.

How many LI atoms are contained in 97.9 of LI?
To determine the number of Li atoms in 97.9 g of Li, you first need to calculate the number of moles of Li using the molar mass of Li (6.94 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of Li to atoms.
How many atoms are in 12.7grams of lithium?
To determine the number of atoms in 12.7 grams of lithium, you need to first calculate the number of moles using the molar mass of lithium (6.94 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert from moles to 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.
How many atoms are in 3.00 moles of Li?
There are 1.81 x 10^24 atoms in 3.00 moles of lithium (Li). This is calculated by multiplying Avogadro's number (6.022 x 10^23 atoms/mol) by the number of moles.
How many moles in 15 grams if lithium?
From the periodic table, lithium has an atomic weight of 6.941. The molar mass of an element is the atomic weight in grams. Therefore, 1 mole Li = 6.941g Li Therefore, moles Li = 15g Li X 1 mole Li/6.941g Li = 2.2 moles Li
