Propane is C3H8
So Molar mass propane = 3*12 + 8*1 = 44 <span>
No. of moles of propane = 167/44 = 3.795 moles</span>
From the stoichiometry: <span>
No. of moles of hydrogen = 3.795 moles * (8 moles
hydrogen / 1 mole propane) = 30.36 moles
Using Avogadros number, 1 mole of any substance
contains 6.022 x 10^23 atoms, therefore:
<span>No. of hydrogen atoms = 30.36 * 6.022 x 10^23 =
1.828 x 10^25 atoms</span></span>
The phenomenon known as "salting-out" occurs at very high ionic strengths, when protein solubility declines as ionic strength rises. As a result, salting out may be used to segregate proteins according to how soluble they are in salt solutions.
Because large levels of sodium chloride disturb the bonds and structure of the active site, the rate of enzyme activity will gradually decrease as the concentration of sodium chloride rises. As a result, some of the active sites get denaturized and the starch loses its ability to attach to them. As more enzymes get denatured and eventually cease to function, enzyme activity will steadily wane.
Answer:
=16.49 L
Explanation:
Using the equation
P1= 0.6atm V1= 30L, T1= 25+273= 298K, P2= 1atm, V2=? T2= 273
P1V1/T1= P2V2/T2
0.6×30/298= 1×V2/273
V2=16.49L
