What it the percentage of sulfur in copper(I) sulfide, Cu2S

see other post. There is no reason to make the same post multiple times. Have patience.

To determine the percentage of sulfur in copper(I) sulfide (Cu2S), we need to calculate the molar masses of copper and sulfur and use them to find the ratio of their masses in the compound.

1. Determine the molar masses of copper (Cu) and sulfur (S):
- The molar mass of copper (Cu) is approximately 63.55 g/mol.
- The molar mass of sulfur (S) is approximately 32.07 g/mol.

2. Calculate the total molar mass of copper(I) sulfide (Cu2S):
- Since the formula for copper(I) sulfide is Cu2S, we have 2 copper atoms and 1 sulfur atom in the compound.
- Multiply the molar mass of copper by 2 and add the molar mass of sulfur to get the total molar mass of Cu2S:
Total molar mass of Cu2S = (2 * molar mass of Cu) + (1 * molar mass of S)

3. Calculate the percentage of sulfur in copper(I) sulfide:
- The percentage of sulfur in Cu2S can be calculated by determining the mass of sulfur in 1 mole of the compound and expressing it as a percentage of the total molar mass.
- Divide the molar mass of sulfur by the total molar mass of Cu2S. Then, multiply the obtained decimal value by 100 to convert it to a percentage.

This calculation will give us the percentage of sulfur in copper(I) sulfide, Cu2S.
