Answer:
Certain types of atoms are "radioactive," meaning that they will eventually decay, or "break down" into a different type of atom. In this activity, you will simulate radioactive decay by flipping coins. Coins that land tails-up "decay," and coins that land heads-up remain the same.

<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.
