In order to find the molarity of the solution, we first require the moles of acetic acid added. For this,we need the mass which is:

Mass = volume * density

Mass = 50 * 1.05
Mass = 52.5 grams


Moles = mass / molecular weight

Moles = 52.5 / 60.05 
Moles = 0.874 mol

Next, we know that the molarity of a solution is:

Molarity = moles / liter
Molarity = 0.874 / 0.5

Molarity = 1.75 M

Answer:

The molarity of a acetic acid solution is 1.530 mol/L.

Explanation:

Mass of the acetic acid = m

Volume of the acetic acid = 50.00 ml

Density of the acetic acid =  d = 1.05 g/mL

Mass = Density × Volume

m=1.05 g/mL\times 50.00 mL=50.5 g

Volume of the water = 500.0 mL

Volume of the solution  = V + v

Volume of the final solution = 50.00 mL + 500.0 mL = 550.0 mL = 0.550 L

Molarity of the solution is the moles of compound in 1 Liter solutions.

Molarity=\frac{\text{Mass of compound}}{\text{Molar mas of compound}\times Volume (L)}

The molarity of a acetic acid solution:

Molarity=\frac{50.5 g}{60g/mol\times 0.550 L}=1.530 mol/L

I think C. Ionic compounds are very difficult to break apart because they are fully negative or positive charges, like magnets.

What is a controlled factor in an experiment?
Romashka-Z-Leto [24]
Sorry this will probably be pretty long.

So think of the "control" as being something you yourself add to increase or decrease the effects in an experiment.
I'll give you an example so it is not as confusing.
Say you have decided to make an experiment on plants. Which plant can grow the fastest on which type of liquid? What is being added to this experiment? The liquid! Or all of the liquids you used. Like if you used Coke, Lime Gatorade, Orange Gatorade, and Water. Each drink will EFFECT each plant differently.

What is the scientific notation of 36000x10 ex.10?
Vedmedyk [2.9K]

Answer:

3.6 times 10^4

Explanation:

Scientific notation is between 1-9. So, we move 36000 to 4 decimal places. SO it would be 3.6 times 10^4. Scientific Notation always has the base of 10 . Enjoy :)
