The molarity of a solution made from 317.5g of AlCl3 with enough water to make 500.0 mL is 4.76M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated by dividing the number of moles of the substance by its volume.
Molarity = no of moles ÷ volume
According to this question, a solution is made from 317.5g of AlCl3 with enough water to make 500.0 mL.
No of moles of AlCl3 = 317.5g ÷ 133.34 g/mol = 2.38 moles
Molarity of AlCl3 solution = 2.38 moles ÷ 0.5L
Molarity = 4.76M
Therefore, the molarity of a solution made from 317.5g of AlCl3 with enough water to make 500.0 mL is 4.76M.

Answer:
Equilibrium in ecology refers to a state that occurs such that a small disturbance or change is counter balanced by another change so that the community is restored to its original state. Thus, as a community goes through multiple changes through each stage of succession, it is not in equilibrium.
Ionic bond<span>, also </span>called<span> electrovalent </span>bond<span> , type of linkage </span>formed<span> from the electrostatic </span>attraction between oppositely charged ions<span> in a chemical compound.
</span>
Since water is already at 100<span>°C all the energy is used to evaporate it.
Now we can calculate how many </span>mols of water are evaporated with 820kJ.
We calculated that we got 20 mols of water evaporated. Now, all we have to do is find how many grams is a mol of water. Molar mass of water is <span>20.16 g/mol.
</span>The final answer is:
Answer:
2.33g of iron (iii) chloride
50.0 mL of 5.00 M of sodium phosphate
FeCl3 + Na3PO4 > Fe(PO4) + 3NaCl
mol = conc × vol = 0.5 × 50/1000 = 0.025 mol Na3PO4
from the equation:
1 mol of Na3PO4 reacts with 1 mol FeCl3 = 3 mol of NaCl
0.025 mol = x
x = 0.0025 × 3 = 0.075 mol NaCl
mass = 0.075 g × 59 g/mol = 4.425 g NaCl
i guessed all of this so i dont know i it is correct
