<u>Answer:</u> The formula for the given compound is
<u>Explanation:</u>
An ionic compound is defined as the compound which is formed when electron gets transferred from one atom to another atom. These are usually formed when a metal reacts with a non-metal.
The chemical formula of copper (I) sulfide is because this is formed by the combination of
ions and
ions
The chemical formula of copper (II) sulfide is because this is formed by the combination of
ions and
ions
To calculate the percent composition of element in a compound, we use the equation:
...........(1)
- <u>For copper (I) sulfide:</u>
Mass of copper = (2 × 63.546) = 127.092 g/mol
Mass of copper (I) sulfide = 159.16 g/mol
Putting values in equation 1, we get:
- <u>For copper (II) sulfide:</u>
Mass of copper = 63.546 g/mol
Mass of copper (II) sulfide = 95.611 g/mol
Putting values in equation 1, we get:
- <u>Given compound:</u>
Mass of copper in given compound = 0.8383 grams
Mass of given compound = 1.0440 grams
Putting values in equation 1, we get:
The percent composition of copper is close to the composition in copper (I) sulfide.
Hence, the formula for the given compound is
