How many moles of carbon are in 3.5 L?
SashulF [63]

Answer:

0.16mole

Explanation:

To solve this problem, we are going to assume that the number of moles of carbon to be determined is that at STP, standard temperature and pressure.

The number of moles of a substance at STP is given as;

 Number of moles  = \frac{volume}{22.4}  

Given volume  = 3.5L

Now, insert the parameters;

     Number of moles  = \frac{3.5}{22.4}   = 0.16mole

Tartaric acid, h2c4h4o6, has two acidic hydrogens. the acid is often present in wines and precipitates from solution as the wine
chubhunter [2.5K]

<em>Balance</em> <em>Chemical equation:</em>

  •                   C4H6O6 + 2NaOH ⇒ Na2C4H4O6 + 2H2O

<em>Given Data:</em>

                       Molarity of NaOH =0.3000

                        Vol. of NaOH = 21.65

<em>Solution:</em>

       moles of NaOH = (0.3000 × 21.65)÷1000 = 0.0064 mol

According to balance chemical equation

                    NaOH :  C4H6O6

                        2     :      1

                   0.0064 = (1/2) ×0.0064 = 0.0032 mol

So these 0.0032 mol of tartaric acid are prsent in 50.0 ml of solution.

So in I littre of solutions, its concentration will be as follow

               M = 0.0032 × 1000/50 = 0.064 M

<em>Result: </em>

  • The concentration of acid will be 0.064 M.
