The molar mass of lithium is approximately 6.94 g/mol.
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.
To determine the grams in 4.500 Li2O (lithium oxide), you need to calculate the molar mass of Li2O. Lithium has a molar mass of approximately 6.94 g/mol and oxygen has a molar mass of approximately 16.00 g/mol. Therefore, the molar mass of Li2O is 14.94 g/mol. To find the grams in 4.500 Li2O, multiply the molar mass by the amount given (4.5 mol * 14.94 g/mol).
The molar mass of lithium (Li) is approximately 6.94 grams per mole.
To find the number of moles in 1.9 g of lithium, you need to divide the mass of lithium by its molar mass. The molar mass of lithium is approximately 6.94 g/mol. So, 1.9 g / 6.94 g/mol ≈ 0.274 moles of lithium.
The molar mass of lithium oxide (Li2O) is calculated by adding the molar masses of lithium (Li) and oxygen (O). Molar mass of Li = 6.94 g/mol Molar mass of O = 16.00 g/mol Molar mass of Li2O = 2*(molar mass of Li) + molar mass of O = 2*(6.94) + 16.00 = 14.88 + 16.00 = 30.88 g/mol
"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.
