A copper sulfate solution contained 0.100 moles of copper sulfate dissolved
1 answer:
The mass copper sulphate CuSO₄ in 30ml solution is 957.6g.
<h3>What is the solution?</h3>A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.
To determine the mass of copper sulphate in the given solution, compare both the molarity given:
M₁V₁=M₂V₂
0.1/0.5=n₂/30 cm³=ml
n₂=6 moles
6×159.5=957.6g
Multiply the calculated moles with the relative mass/molecular mass to get the mass of CuSO₄.
Hence, the mass of CuSO₄ is 957.6g

Answer:
Explanation:
1. Calculate the initial moles of acid and base
2. Calculate the moles remaining after the reaction
OH⁻ + H₃O⁺ ⟶ 2H₂O
I/mol: 0.0053 0.005 00
C/mol: -0.00500 -0.005 00
E/mol: 0.0003 0
We have an excess of 0.0003 mol of base.
3. Calculate the concentration of OH⁻
Total volume = 53 mL + 25.0 mL = 78 mL = 0.078 L
