The Correct Answer and Explanation is :
o calculate the molar mass of lithium carbonate (Li₂CO₃), a compound commonly used in the treatment of bipolar disorder, follow these steps:
1. Determine the Molar Mass of Each Element:
- Lithium (Li): he atomic mass of lithium is approximately 6.94 grams per mole (g/mol).
- Carbon (C): he atomic mass of carbon is approximately 12.01 g/mol.
- Oxygen (O): he atomic mass of oxygen is approximately 16.00 g/mol.
2. Multiply Each Molar Mass by the Number of Atoms in the Formula: - Lithium: i₂CO₃ contains 2 lithium atoms.
- Calculation: atoms × 6.94 g/mol = 13.88 g/mol
- Carbon: i₂CO₃ contains 1 carbon atom.
- Calculation: atom × 12.01 g/mol = 12.01 g/mol
- Oxygen: i₂CO₃ contains 3 oxygen atoms.
- Calculation: atoms × 16.00 g/mol = 48.00 g/mol
3. Sum the Total Molar Mass: - Total Molar Mass: 3.88 g/mol (Li) + 12.01 g/mol (C) + 48.00 g/mol (O) = 73.89 g/mol
herefore, the molar mass of lithium carbonate (Li₂CO₃) is 73.89 g/mol.
Explanation:
he molar mass of a compound is the sum of the atomic masses of all the atoms present in its chemical formula.ach element’s atomic mass represents the mass of one mole of its atoms, measured in grams per mole (g/mol).y multiplying the atomic mass of each element by the number of times it appears in the compound’s formula and then summing these values, we obtain the compound’s molar mass.
n the case of lithium carbonate, the formula Li₂CO₃ indicates that each molecule consists of two lithium atoms, one carbon atom, and three oxygen atoms.y calculating the contribution of each element to the total mass and adding them together, we determine that the molar mass of lithium carbonate is 73.89 g/mol.
nderstanding the molar mass is crucial in chemistry, especially when dealing with chemical reactions and stoichiometry.t allows chemists to convert between the mass of a substance and the amount in moles, facilitating accurate measurements and predictions in chemical processes.
