Lithium Selenide has a molar mass of 93
"The amount of grams in one mole a substance" is themolar mass (the mass of 1 mole) of a substance.The molar mass of Lithium oxide (Li2O) is 29.881 g/molThe 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/molNotes:* 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.
Lithium selenide, Li2Se
Lithium is +1 and Selenium is -2, so Li2Se (Lithium Selenide). Check out the related link. You can type in the chemical formula LI2SE, and it will give you the molecular weight (mass) and also the name of the compound (if it is a named compound). Like try H2SO4 and it tells you Sulfuric Acid. Note: you have to scroll about half way down to get past all of the advertisements.
LiCIO is lithium hypochlorite. It is white in color, gives off the odor of chlorine, and has a molar mass of 58.39 grams per mole.
The molar mass of glucose is 180,16 g.
Lithium's molar mass is 6.941g/mol. To find the molar mass of an element, take the atomic weight on the periodic table in grams.
Lithium has a molar mass of 6.94 g/mol. Oxygen has a molar mass of 16.00 g/mol. Since Lithium Oxide has 2 Lithium atoms, the molar mass is: (6.94 x 2) + 16.00 = 29.88 g/mol.

Lithium selenide, Li2Se
Well Sodium Selenide has a formula of Na2Se. Let's take a look at their molecular massesMolecular Mass of Sodium = 22.99=> 2 Sodiums = 45.98gMolecular Mass of Selenide = 78.96=> The Total Molecular Mass is 45.98 + 78.96 = 124.94 g mol-1What does that figure mean?This is the amount of Sodium Selenide that is required to make a 1 mole solution of this substance in a litre of water.
molar mass of lithium is 6.941 1.9g/6.941=0.273 answer= 0.273 moles
sodium iodide
Multiply by molar mass.0.0295*6.9412=0.2048g
The mass of 0.100 mole of lithium is 0,6941 g. This can be calculated from this equation: m=n*M where m is mass in grams, n is amount of unit in mole and M is molar mas in gram/mole. the molar mass can be found in periodic table, for lithium it is 6,941 g/mol
Molecular weight calculation: 6.941*2 + 32.065 + 15.9994*4
