Hey there!

Find molar mass of H₂SO₄

H: 2 x 1.008

S: 1 x 32.065

O: 4 x 16

--------------------

        97.073 grams/mole

We have 196 grams.

97.073 ÷ 196 = 0.495  

196 g of H₂SO₄ is 0.495 moles.

Hope this helps!

Calculate the pH of a solution made by adding 59 g of sodium acetate, NaCH3COO, to 23 g of acetic acid, CH3COOH, and dissolving
Elza [17]

This is an incomplete question, here is a complete question.

Calculate the pH of a solution made by adding 59 g of sodium acetate, NaCH₃COO, to 23 g of acetic acid, CH₃COOH, and dissolving in water to make 400. mL of solution. Hint given in feedback. The Ka for CH₃COOH is 1.8 x 10⁻⁵ M. As usual, report pH to 2 decimal places.

Answer : The pH of the solution is, 4.97

Explanation :

First we have to calculate the moles of CH₃COOH and NaCH₃COO

\text{Moles of }CH_3COOH=\frac{\text{Given mass }CH_3COOH}{\text{Molar mass }CH_3COOH}=\frac{23g}{60g/mol}=0.383mol

and,

\text{Moles of }CH_3COONa=\frac{\text{Given mass }CH_3COONa}{\text{Molar mass }CH_3COOH}=\frac{59g}{82g/mol}=0.719mol

Now we have to calculate the value of pK_a.

The expression used for the calculation of pK_a is,

pK_a=-\log (K_a)

Now put the value of K_a in this expression, we get:

pK_a=-\log (1.8\times 10^{-5})

pK_a=5-\log (1.8)

pK_a=4.7

Now we have to calculate the pH of the solution.

Using Henderson Hesselbach equation :

pH=pK_a+\log \frac{[Salt]}{[Acid]}

pH=pK_a+\log \frac{[CH_3COONa]}{[CH_3COOH]}

Now put all the given values in this expression, we get:

pH=4.7+\log (\frac{0.719}{0.383})

(As the volume is same. So, we can write concentration in terms of moles.)

pH=4.97

Therefore, the pH of the solution is, 4.97

CH3CH2OH + 302 → 2002 + 3H20
Softa [21]

Answer:

Oxygen gas

Explanation:

 Given expression:

          CH₃CH₂OH + 3O₂ → 2CO₂ + 3H₂O

Number of moles of oxygen gas  = 1 mole

Number of moles of ethanol = 1 mole

Unknown:

The limiting reactant  = ?

Solution:

The limiting reactant is the reactant in short supply in a chemical reaction. To find this specie, we always us the number of moles.

  From the equation of the reaction:

        1 mole of ethanol would require 3 moles of oxygen gas

 But we have been given just 1 mole of oxygen gas instead of 3moles.

 Therefore, oxygen gas is the limiting reactant.
