The chemical formula for this compound : Cu₂SO₄-Copper(I) sulfate
<h3>Further explanation</h3>
Given
2 atoms of Copper, 1 atom of Sulfur and 4 atoms of Oxygen.
Required
The chemical formula
Solution
The number of atoms forming a compound is usually indicated from the subscript in the formula
From the problem it can be seen that the compound has:
2 atoms of Cu, 1 atom of S, and 4 atoms of O
So the formula:
<em>Cu₂SO₄</em>
When the concentration is expressed in mass percentage, that means there is 3 g of solvent H₂O₂ in 100 grams of the solution. Then, that means the remaining amount of solute is 97 g. We use the value of molarity (moles/liters) to determine the amount of solution in liters, denoted as V. The solution is as follows:
0.02 mol KMnO4/L solution * 158.034 g KMnO4/mol * V = 97 g KMnO4
Solving for V,
V = 30.69 L
Answer: they have the same mass
Explanation:weight is calculated
