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.

I would say B but that may not be correct, as I didn't do a full calculation
In molten lava like all the rest.
Hope it helped!!!
Answer: 800 mL of methyl alcohol should be added to 200 ml of water to make this solution.
Explanation:
Volume of the methyl alcohol = x
Volume of water = y = 200 mL
Volume of the solution ,V = x + y
Volume percentage of solution = 80%
x = 800 mL
800 mL of methyl alcohol should be added to 200 ml of water to make this solution.
1. First, move the decimal place until you have a number between 1 and 10. If you keep moving the decimal point to the right in 0.0000073 you will get 7.3.
2. Next, count how many places you moved the decimal point.
