Answer:
The new pressure is 44.4 kPa.
Explanation:
We have,
Initial volume,
Initial pressure,
It is required to find the new pressure when the volume is increased to 50 ml. The relationship between pressure and volume is known as Boyle's law.
is final pressure
So, new pressure is 44.4 kPa.
moles Cu produced : 0.002
<h3>Further explanation</h3>Concentration of copper sulfate (CuSO₄) : 0.319 g/dm³
MW CuSO₄ :
mol CuSO₄ /dm³ :
CuSO₄⇒Cu²⁺ + SO₄²⁻
mol Cu : mol CuSO₄ = 1 : 1 , so mol Cu²⁺=0.002
