"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.

0,0864 moles of lithium contain 0,6 g Li.
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 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 grams of Li3N can be formed from 1.75 moles of Li?
20,32 g of lithium nitride can be obtained.

How many grams does 3.0 moles of He gas weigh?
In order to figure this out, you must do dimensional analysis. Here it is: 3.0 moles He x 4.0026 grams/ mole He = 12 grams
If you need 5 moles of sulphuric acid how many grams of it will you weigh?
The mass of sulfuric acid is 490,395 grams.
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
