D = m / V
13.6 = 8.3 / V
V = 8.3 / 13.6
V = 0.610 mL

Answer:
18.9 moles
Explanation:
We have the following data:
V = 50 L
P = 12.4 atm
T= 127°C + 273 = 400 K
R = 0.082 L.atm/K.mol (it is the gas constant)
We use the ideal gas equation to calculate the number of moles n of the gas:
PV = nRT
⇒ n = PV/RT = (12.4 atm x 50 L)/(0.082 L.atm/K.mol x 400 K) = 18.9 mol
Answer: 97.2223 ml
Explanation:
The rule that we will use to solve this problem is:
M2*V1 = M2*V2 where:
M1 is the initial concentration = 3.5 m
V1 is the initial volume = 0.25 l = 250 ml
M2 is the final concentration = 9 m
V2 is the final volume that we need to find
Substitute with the givens in the above equation to get V2 as follows:
3.5*250 = 9*V2
V2 = <em><u>97.2223 ml</u></em>
Both strong acid and strong base will alter the solubility and the nature of a protein. This is because, adding a strong acid or base to a protein will drastically change the pH of the protein and this will leads to formation of precipitation and denaturation of the protein.
