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:
- <u>1.29 mol</u>
Explanation:
This is a direct application of the equation for ideal gases.
Where:
- P = pressure = 1.25 atm
- V = volume = 25.2 liter
- R = Universal constant of gases = 0.08206 atm-liter/K-mol
- T = absolute temperature = 25.0ºC = 25 + 273.15 K = 298.15 K
- n = number of moles
Solving for n:
Substituting:
