Hello!

You'll need 20 mL of 0,20 M NaOH to react completely with 100 mL of 0,040 M Acetic Acid. 

The reaction between NaOH and Acetic Acid is the following:

NaOH + CH₃COOH → H₂O + CH₃COONa

To calculate the volume of 0,20 M NaOH needed to react completely with 100 mL of 0,040 M Acetic Acid, we'll need to use the following equation (Molar equivalence) and clear for Volume of NaOH:

M_{NaOH}*V_{NaOH}=M_{CH_3COOH}*V_{CH_3COOH} \\  \\  V_{NaOH}= \frac{M_{CH_3COOH}*V_{CH_3COOH} }{M_{NaOH}} \\  \\  V_{NaOH}= \frac{0,040M*100 mL }{0.20}}=20 mL

Have a nice day!

Determine the number of molecules in a 100. gram sample of CCl4
enyata [817]
100. g CCl4* (1 mol CCl4/ 153.8 g CCl4)* (6.02*10^23 CCl4 molecules/ 1 mol CCl4)= 3.91*10^23 CCl4 molecules.
(Note that the units cancel out so you get the answer)

Hope this helps~

Determine the number of atoms in a 48.3-g sample of zinc. express your answer in zinc atoms using scientific notation.
Paladinen [302]
To answer this question, you need to know the molecular weight of zinc so you can determine how many mol zinc you have. Zinc molecular weight is 65.38gram/mol. Then the calculation would be: 48.3gram/(<span>65.38gram/mol)= 0.74 mol

Since you are asked the amount of atom, you need to multiply the unit in mole with Avogadro number. The calculation should be: 0.74 * 6.02 * 10^23= 4.45* 10^23 molecules</span>
