Chemistry
1 answer:
Brums [2.3K]3 years ago
3 0

Answer:

1812g

Explanation:

So molarity is moles/litres or M= mol/liter (lets apply this formula to find moles)

M=mol/L

1.99=mol/2.66

Moles= 5.2934 moles of C12H22O11

Next step is quite simple, we know molar mass of C12H22O11 is 342.3 g/mol so we simply multiply the moles we get to molar mass we are left with the grams needed,

5.2934 moles of C12H22O11 * 342.3 g C12H22O11 /mol = 1812g

(I have left out decimal places, you can caculate this and add them if you desire)

Acetic acid is a weak acid with a pKa of 4.76. What is the concentration of acetate in a buffer solution of 0.2M at pH 4.9. Give
Ghella [55]

Answer:

[base]=0.28M

Explanation:

Hello,

In this case, by using the Henderson-Hasselbach equation one can compute the concentration of acetate, which acts as the base, as shown below:

pH=pKa+log(\frac{[base]}{[acid]} )\\\\\frac{[base]}{[acid]}=10^{pH-pKa}\\\\\frac{[base]}{[acid]}=10^{4.9-4.76}\\\\\frac{[base]}{[acid]}=1.38\\\\

[base]=1.38[acid]=1.38*0.20M=0.28M

Regards.
