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.
The molar mass of lithium oxide (Li2O) is 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).
This suggests the substance is lithium oxide (Li2O). The molar mass of Li2O is 29.88 g/mol. Therefore, 62g of Li2O is equivalent to 2.07 moles (62g / 29.88 g/mol = 2.07 mol).
The molar mass of Li = 6.941 g/mol

This suggests the substance is lithium oxide (Li2O). The molar mass of Li2O is 29.88 g/mol. Therefore, 62g of Li2O is equivalent to 2.07 moles (62g / 29.88 g/mol = 2.07 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.

When lithium reacts with oxygen, the mass of the lithium is unchanged. However, the mass of lithium oxide (Li2O) created is about 2.1 times as great as the starting mass of lithium metal (110% increase), due to the addition of oxygen. If the lithium reacts with nitrogen, the mass of lithium is similarly unchanged. The reaction produces lithium nitride (Li3N), with a mass about 1.7 times as great as the starting mass of lithium metal (67% increase), due to the addition of nitrogen.
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
To determine the amount of lithium oxide (Li2O) required to remove 75.0 kg of water, we first need to know the stoichiometry of the reaction involved in water removal. Typically, Li2O reacts with water to form lithium hydroxide (LiOH). The reaction is: [ \text{Li}_2\text{O} + \text{H}_2\text{O} \rightarrow 2\text{LiOH} ] From the balanced equation, 1 mole of Li2O reacts with 1 mole of water. The molar mass of Li2O is approximately 29.88 g/mol. Thus, for 75.0 kg (or 75,000 g) of water, you need around 2,513.4 g of Li2O, calculated using the molar ratios and the respective molar masses.
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.
