Sodium iodide has the highest molar mass among the compounds listed, with a molar mass of 149.89 g/mol. Sodium bromide has a molar mass of 102.89 g/mol, sodium chloride has a molar mass of 58.44 g/mol, lithium bromide has a molar mass of 86.85 g/mol, and lithium fluoride has a molar mass of 25.94 g/mol.
To find the molar mass of beryllium oxide (BeO), you will need to determine the individual molar masses of beryllium (Be) and oxygen (O) from the periodic table and then add them together. The molar mass of Be is about 9 g/mol and the molar mass of O is about 16 g/mol. When you add them together, you'll find that the molar mass of BeO is approximately 25 g/mol.
The molarity of the solution can be calculated by first finding the moles of lithium fluoride using its molar mass, which is 25.94 g/mol for lithium and 19.00 g/mol for fluorine. Add these together to find the molar mass of lithium fluoride. Then, divide the mass of lithium fluoride by its molar mass to get the moles. Finally, divide the moles by the volume of the solution in liters to get the molarity.
The balanced chemical equation for the reaction between water and Li2O is 2 H2O + Li2O -> 2 LiOH. It shows that 2 moles of water react with 1 mole of Li2O. So, 2.2 moles of Li2O would require 4.4 moles of water for complete reaction.
To calculate the mass of sodium needed to produce 108.2 g of sodium oxide, you need to determine the molar mass ratio between sodium and sodium oxide. Sodium oxide has a molar mass of 61.98 g/mol, while sodium has a molar mass of 22.99 g/mol. Using stoichiometry, you can calculate that you need (2 * 22.99) g of sodium to produce 108.2 g of sodium oxide.
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).
The mass of lithium oxide (Li2O) is 8,o9 g.
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.
The molar mass of lithium (Li) is approximately 6.94 grams per mole.

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.
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.
The molar mass of lithium is 6.94 g/mol. Thus, for 3 moles of lithium, the mass would be: 3 moles x 6.94 g/mol = 20.82 grams of lithium.
The molar mass of lithium is approximately 6.94 g/mol.
The molar mass of lithium selenide (Li2Se) can be calculated by adding the atomic masses of lithium and selenium together. The atomic mass of lithium is approximately 6.94 g/mol, and the atomic mass of selenium is approximately 78.97 g/mol. Therefore, the molar mass of lithium selenide is approximately 163.85 g/mol.
