A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one thus equalizing the concentrations on each side of the membrane. I hope this helps :D
Answer:
pH = - log [concentration]
pH = - log (0.0043M)
pH = 2.37
<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.
Nope, it actually means the exact opposite.
Solubility
the ability to be dissolved, especially in water

Answer:
Theoretical yield = 4.09 g water.
75% yield = 3.07g water.
Explanation:
C3H8 + 5O2 ---> 3CO2 + 4H2O
Using atomic masses:
(12 *3 + 8 * 1.008) g C3H8 yield (theoretically) (4* (2*1.008 + 16) g water
44.06g C3H8 yields 72.06g water
So 2.5 g yields (72.06/44.06) * 2.5
= 4.09 g water.
If the yield is 75% then it is 4.09 * 0.75
= 3.07 g water.
