"The amount of grams in one mole a substance" is the
molar mass (the mass of 1 mole) of a substance.
The molar mass of Lithium oxide (Li2O) is 29.881 g/mol
The molar mass of a compound can be calculated by adding the molar masses of the compound's constituent elements.
In this case :
molar mass of lithium oxide= 2x(molar mass of lithium)+ (molar mass of oxygen)
= 2x(6.941) + 15.999
=29.881 g/mol
Notes:
* the molar masses of elements are found in the Periodic Table. * Notice the subscript "2" in the chemical formula of lithium oxide , Li2O. This subscript indicates that two lithium atoms are involved in each lithium oxide atom.Hence, we multiply the molar mass of of lithium by "2" when calculating lithium oxide's molar mass.

120 grams of calcium contain 2,994 moles.
How many grams are in 0.0864 moles of lithium?
To convert moles to grams, you need to know the molar mass of lithium, which is approximately 6.94 g/mol. Multiplying the number of moles (0.0864 mol) by the molar mass (6.94 g/mol) gives you approximately 0.6 grams 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 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
How many grams of lithium bromide are present in 25.0 mL of a 0.100 M soution?
To calculate the grams of lithium bromide present in the solution, you would first determine the moles of lithium bromide using the formula: moles = Molarity x Volume (L). Once you have the moles, you can convert it to grams using the molar mass of lithium bromide (86.85 g/mol).

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 grams of lithium sulfide must be dissolved in 1600 grams of water to make a 2 molal solution?
To make a 2 molal solution, you would need 2 moles of lithium sulfide per 1000g of water. Since you have 1600g of water, you need 2 x (1600 / 1000) = 3.2 moles of lithium sulfide. To find the grams needed, you would multiply the molar mass of lithium sulfide (45.94 + 32.06) by the number of moles needed (3.2) to get 149.12 grams.
