Copper(I) compounds in aqueous solutions are unstable and disproportionate:
Cu₂SO₄ = Cu + CuSO₄
Necessary for dissolution of non-aqueous solvent.
M(Cu₂SO₄)=223.16 g/mol
m(Cu₂SO₄)=14.1 g
v=0.250 L
n(Cu₂SO₄)=m(Cu₂SO₄)/M(Cu₂SO₄)
c=n(Cu₂SO₄)/v=m(Cu₂SO₄)/(vM(Cu₂SO₄))
c=14.1/(0.250*223.16)=0.253 mol/L
0.253 M
The percentage of Carbon (C) present in one molecule of
Dichlorodifluoromethane (CF₂Cl₂) : 10%
<h3>Further explanation</h3>
Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
With this law, we can calculate how many grams an element is needed to make a compound with a certain mass, as desired
MW Dichlorodifluoromethane (CF₂Cl₂) :
=12+2.19+2.35=120 g/mol
Answer:
Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis.
