How many atoms are in 2.5 mole of hydrogen?
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
How many moles are contained in 25.0 grams of lithium?
15g Li * (1mol Li / 6.941g Li) = 2.16 mol Li
How many moles of N2 are needed to react with 0.500 mol of Lithium?
The balanced chemical equation for the reaction of lithium and nitrogen to form lithium nitride is 6Li + N2 -> 2Li3N. From the equation, it shows that 1 mole of N2 reacts with 6 moles of Li. Therefore, to react with 0.500 mol of Li, you would need 0.500 mol of N2.
How many atoms are there in 34 grams of lithium?
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

3,00 moles of Li have 18,066422571.10e23 atoms.
How many moles of BaCOsub3 are found in 3.4910pow18 atoms of Li?
No moles of BaCO3 are found in any amount of Li.
How many moles are in Li2O?
1 mole of Li₂O contains 2 moles of lithium (Li) atoms and 1 mole of oxygen (O) atoms. Therefore, in 1 mole of Li₂O, there are a total of 3 moles of atoms.
How many atoms are in 4.7 mole LI?
4.7 mole Li (6.022 X 10^23/1 mole Li) = 2.8 X 10^24 atoms Li
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 ---------------------------------------

Number of Li atoms in 4.5 moles of Li?
Oh, dude, you're hitting me with that chemistry question! So, like, one mole of any element contains Avogadro's number of atoms, which is 6.022 x 10^23. In this case, you've got 4.5 moles of Li, so you just multiply that by Avogadro's number to get the total number of Li atoms. That's like... a lot of Li atoms, man.
How many atoms are present in 27.0 g Li?
1 mole Li = 6.94g Li = 6.022 x 1023 atoms Li 27.0g Li x 6.022 x 1023 atoms Li/6.94g Li = 2.34 x 1024 atoms Li
How many moles of lithium would react with 4 moles of phosphoric acid?
The balanced chemical equation for the reaction is 3Li + H3PO4 -> Li3PO4 + 3H2. The mole ratio is 1:1 between Li and H3PO4. Therefore, 4 moles of H3PO4 will react with 4 moles of Li.
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 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
