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

An electrode has a potential of 1.201 V with respect to a saturated silver-silver chloride electrode. What would the electrodes
fredd [130]

Answer:

The potential wrt. calomel is 1.254 V

Explanation:

Given:

Potential wrt. silver chloride E_{Ag}  = 1.201 V

Potential wrt. saturated silver chloride E = 0.197 V

Potential wrt. SCE E_{Hg} = 0.241 V

Now potential wrt. hydrogen is given by,

   = 1.201- 0.197

   = 1.004 V

And we find for potential wrt. calomel,

   = potential wrt. hydrogen + potential wrt. SEC

   = 1.004 +0.241

   = 1.254 V

Therefore, the potential wrt. calomel is 1.254 V

AleksAgata [21]
Answer:
Na2O+H2O=2NaOH
Step by step exp.
Given:
Equation Na2O+H2O=NaOH
To find: Balance the equation
Solution:
Taking LHS of the equation
LHS=Na2O+H2O
There is 2 sodium, 2 oxygen,& 2 hydrogen
To balance the equation we have equal number of atom so we multply 2 to the RHS=2NaOH
There fore the equation form is
Na2O+H2O=2NaOH
