3,00 moles of Li have 18,066422571.10e23 atoms.
3 moles Li x 6.02x10^23 atoms/mole = 1.8x10^24 atoms
2.7×1024 atoms
0.106 moles Lithium (6.022 X 1023/1 mole Li) = 6.38 X 1022 atoms of Lithium ======================
12 moles Li
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
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.
85 moles Li x 6.02x10^23 atoms/mole Li = 5.17x10^25 atoms of Li
How many lithium atoms are in 10.56 g of lithium
No moles of BaCO3 are found in any amount of Li.
2.7×1024 atoms
For this problem, the atomic mass is not required. Take the mass in moles and multiply it by Avogadro's constant, 6.02 × 1023. Divide by one mole for the units to cancel.2.5 moles H2 × (6.02 × 1023 atoms) = 1.51 × 1024 atoms
Li atomic mass= 6.941g/mol= 4.9 moles of Li1.00 mol = 6.02 x 1023 atoms4.9 mol Li = 2.95 x 1024 atoms= 3.0 x 1024 atoms
