What is the percentage distribution of different elements in a different compound, given its molar mass and mass percentage of each element?

To determine the percentage distribution of different elements in a compound, given its molar mass and the mass percentage of each element, you can follow these steps:

1. Determine the molar masses of the elements present in the compound using the periodic table. The molar mass of an element is the mass of one mole of atoms of that element.

2. Convert the mass percentages of each element into grams. For example, if the mass percentage of element A is given as 40%, and the total mass of the compound is 100 grams, then the mass of element A would be 40 grams.

3. Divide the mass of each element by its molar mass to find the number of moles of each element present in the compound. This can be done using the formula: Moles = Mass / Molar Mass.

4. Calculate the total number of moles present in the compound by summing up the moles of all the elements.

5. Finally, calculate the percentage distribution of each element by dividing the number of moles of each element by the total number of moles and multiplying by 100.

For example, let's say we have a compound with a molar mass of 180 g/mol. The mass percentages of element A and element B are 40% and 60%, respectively.

1. Determine the molar masses of element A and element B.

2. Convert the mass percentages into grams. If the total mass of the compound is 100 grams, then the mass of element A would be 40 grams, and the mass of element B would be 60 grams.

3. Divide the masses of each element by their respective molar masses to find the number of moles of each element.

4. Calculate the total number of moles by summing up the moles of each element.

5. Finally, calculate the percentage distribution of each element by dividing its moles by the total moles and multiplying by 100.
