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:

9.0 moles of CaO

Explanation:

We have the reaction equation as follows;

Fe2O3 + Ca3(PO4)2 -------> 2FePO4 + 3CaO

Now we know from the equation that;

1 mole of iron III oxide yields 3 moles of CaO

Therefore;

3 moles of iron III oxide yields 3 * 3/1

= 9.0 moles of CaO

Does the size of an object<br> affect its rate of fall?

Vitek1552 [10]

Answer:

The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration
