Answer

Calculating the Minimum Molecular Mass of a Compound Containing 7% Sodium
- To determine the minimum molecular mass of a compound containing 7% sodium, we need to consider the atomic masses of the elements present in the compound.
- Sodium has an atomic mass of approximately 23 g/mol.

Calculating the Minimum Molecular Mass:
1. Determine the atomic mass contribution of sodium:
- Since the compound contains 7% sodium, the atomic mass contribution of sodium would be 7% of 23 g/mol.
- 7% of 23 g/mol = 0.07 * 23 = 1.61 g/mol
2. Determine the atomic mass contribution of other elements:
- The remaining 93% of the compound is made up of other elements.
- Let's assume the other elements have an average atomic mass of x g/mol.
3. Setting up an equation:
- The total atomic mass contribution of all elements in the compound should add up to the minimum molecular mass.
- 1.61 g/mol (sodium) + 0.93x g/mol (other elements) = Minimum Molecular Mass
4. Calculate the minimum molecular mass:
- To find the minimum molecular mass, we need to find the value of x that satisfies the equation.
- Minimum Molecular Mass = 1.61 + 0.93x
5. Conclusion:
- By calculating the minimum molecular mass using the percentage of sodium and the assumed atomic mass of other elements, we can determine the minimum molecular mass of the compound.
