<h3>Answer:</h3>

C6H12O6

Explanation:

To find empirical formular you write out the element

Carbon Hydrogen Oxygen

3.96 769 5.28

then u althrough divide by their atomic numbers

3.96÷ 12 769÷1 5.28÷16

=0.33 =769 =0.33

also divide althrough by the lowest number

the lowest number is 0.33 so we use it to divide

0.33÷0.33. 769÷0.33. 0.33÷0.33

= 1 = 2 = 1

empirical formular= CH2O

To find the Molecular formular

Molecular number = molar mass

(CH2O)n = 182

(12+1×2+16)n = 182

30n = 182

n = 6

therefore the Molecular formular is C6H12O6

Phenolphthalein is an indicator that turns from colorless (acidic form) to magenta (basic form) and has a pKa of 9.40. What is t
frosja888 [35]

Answer:

40:1  is the ratio of the magenta phenolphthalein concentration to the colorless phenolphthalein concentration.

Explanation:

To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:

pH=pK_a+\log(\frac{[salt]}{[acid]})

pH=pK_a+\log(\frac{[magenta(Php)]}{[Php]})

We are given:

pK_a = negative logarithm of acid dissociation constant of phenolphthalein = 9.40

[magenta(Php)] = concentration of magenta phenolphthalein

[Php] = concentration of colorless phenolphthalein

pH = 11

Putting values in above equation, we get:

11=9.40+\log(\frac{[magenta(Php)]}{[Php]})

\log(\frac{[magenta(Php)]}{[Php]})=11-9.40=1.6

\frac{[magenta(Php)]}{[Php]}=10^{1.6}=39.81 :1 \approx 40:1

40:1  is the ratio of the magenta phenolphthalein concentration to the colorless phenolphthalein concentration.
