First let us compute for the number of moles of butane
(molar mass = 58.12 g/mol)
number of moles = 145 g / (58.12 g/mol) = 2.49 mol
<span>We use the ideal
gas equation to calculate the volume:</span>
<span> V = n R T / P</span>
V = 2.49 mol * 62.36367 L torr / mol K * 308.15 K / 745
torr
<span>V = 64.35 L</span>
50 mL of 2.0 M of
and 25 mL of 2.0 M of
were mixed to make a solution
Final volume of the solution after dilution = 200 mL (given)
Final concentration of
, [
] = 
Final concentration of
, [
] = 
Using Hasselbach- Henderson equation:
![pH = pK_a+ log \frac{[salt]}{[acid]}](https://tex.z-dn.net/?f=pH%20%3D%20pK_a%2B%20log%20%5Cfrac%7B%5Bsalt%5D%7D%7B%5Bacid%5D%7D)

Substituting the values:



Hence, the
of the final solution is 7.15.
Answer:As nouns the difference between winnowing and sieving. is that winnowing is the act of separating chaff from grain while sieving is the act of passing something through a sieve. ... Winnowing is used to separate heavier and lighter components of a mixture by wind or blowing air.
