To work this out, the stoichiometry formula n=m/M will be used. as the Atomic Mass of lithium is 6.941, the equation would be stated as, n=6/6.941.
this equals 0.864429Mol. however this would be written as 0.9 mol due to significant figures.

∙ 15y agoFor this you need the atomic mass of Li. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.
6.35 grams Li / (6.94 grams) = .915 moles Li

1 Lithium reacts spontaneously with Bromine to produce Lithium bromide Write the balanced chemical equation for the reaction If 25.0 g of Lithium and 25.0 g of Bromine are present at the beginning?
2 Li + Br2 = 2 LiBr is the balanced reaction eq'n. For the second part you need to calculate the moles. moles(Li) = 25 / 7 = 3.57 moles(Br2) = 25 / )80 x 2) = 0.15 BY mathematical equivalence of the reaction eq'n 2:1::2 = 0.3:0.15 :: 0.3 So only 0.3 moles (LI) will be reacted, leaving ( 3.57 - 0.3 = 3.27 moles) unreacted. ( That 22.85 g lithium unreacted) It will give a product mass of 7.2 g (LiBr)
How many moles of carbon are in 11.5 g of ibuprofen?
The number of moles of carbon in 11,5 g of ibuprofen is 0,725.
How many atoms of lithium are in 18.7 g?
The gram Atomic Mass of lithium is 6.941; this is the amount of lithium that contains Avogadro's Number of atoms. Therefore, in 18.7 g of lithium, there will be (18.7)/(6.941) times Avogadro's Number of atoms, or about 1.62 X 1024, to the justified number of significant digits.
What is the number of moles of 27.6 g of lithium Li?
3.977 mol
What is the number of moles of 27.6 g of lithium (li)?
3.977 mol
How many grams are in 0.0864 moles of lithium?
0,0864 moles of lithium contain 0,6 g Li.

0.0000639mol
How many moles are in 1.9 g of lithium?
molar mass of lithium is 6.941 1.9g/6.941=0.273 answer= 0.273 moles
A student weighed 0.550 grams of lithium chloride LiCl to use in a reaction How many moles is this?
how many moles in 0.550 g of lithium
How many moles of Li atoms are in 10.56grams of Li?
How many lithium atoms are in 10.56 g of lithium
How many grams are in 3 moles of lithium?
to get the answer just take number of moles you have and multiply it by the molecular mass of the compound which is 22g/mol in lithium oxide's case. 23mol x 22g/mol = 506 g of Li2O
How much would 5.0 moles of lithium weigh in gram?
5.0 mol Li * 6.941 g/mol Li = 34.705 = 35 g Lithium
How many moles are in 56.3grams of Li2SO4?
To determine the number of moles in 56.3 grams of Li2SO4, you need to know the molar mass of Li2SO4 which is approximately 109.9 g/mol. Use the formula: moles = mass/molar mass. Therefore, moles = 56.3 g / 109.9 g/mol = 0.512 mol.
How is a number of moles of an element determined from a known mass?
The number of moles is mass in g/molar mass in g.
If you have g of beryllium how many moles is this equivalent to?
The formula is: number of moles = g Be/9,012.
