Answer:
Malachite green has highest percentage of copper.
Explanation:
Azurite:
Molar mass of Azurite = M = 344.67 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Azurite :
The percentage of copper in an azurite is 55.31%.
Malachite:
Molar mass of Malachite = M = 221.12 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Malachite:
The percentage of copper in an malachite is 57.48%.
Answer:
Final pressure = 362.7 Pa
Explanation:
Given that,
Initial volume, V₁ = 930 ml
Initial pressure P₁ = 156 Pa
Final volume, V₂ = 400 mL
We need to find the final pressure. We know that the relation between volume and pressure is inverse i.e.
So, the final pressure is equal to 362.7 Pa.
