Answer:
mook passes between the earth and sun
Answer:
1048 mL
Explanation:
Step 1: Given data
- Concentration of the solution: 0.2560 M
- Mass of KCl (solute): 20.00 g
Step 2: Calculate the moles corresponding to 20.00 g of KCl
The molar mass of KCl is 74.55 g/mol.
20.00 g × 1 mol/74.55 g = 0.2683 mol
Step 3: Calculate the volume of the solution
Molarity is equal to moles of solute divided by liters of solution.
M = moles of solute / volume of solution
volume of solution = moles of solute / M
volume of solution = 0.2683 mol / (0.2560 mol/L)
volume of solution = 1.048 L = 1048 mL
Answer:
6.25e-6 is the value of the equilibrium constant
Explanation:
we have this equation

When at a state of equilibrium,
we have the concentration of Pb^2+ to be 0.01
we have the concentration of Br^- to be 0.025
the equilibrium constant concentration of both pure solids and liquid s are said to be equal to 1
[PbBR2] = 1
such tht
Keq = [Pb^2+] x [Br-]^2
we already know the values of these from the above.
0.01x0.025^2
= 0.01 x 0.000625
= 0.00000625
= 6.25 x 10^-6
= 6.25e^-6
Explanation:
Dimethylamine
Dimethylamine is a colorless liquid or gas with a fishy or Ammonia-like odor. It is used as a solvent and in making rubber, textiles, drugs, and other chemicals.
