plleaaseee hhelppp What is the molarity of a solution made from 317.5g of AlCl3 with enough water to make 500.0 mL?
Nataliya [291]

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.

1. What is the relationship between ecological succession and equlibrium in an ecosystem?
alexandr1967 [171]

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.

A sample of water at 100°C is converted to steam after absorbing 820 kJ of heat. How grams of H2O are contained in the sample? A
Varvara68 [4.7K]
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.
N= \frac{820}{41} =20 mol
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:
m=20*20.16=403.2g

You react 2.33 g of iron (III) chloride with 50.0 mL of 0.500 M solution of sodium phosphate to
nikklg [1K]

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
