Immunoglobulin G (IgG), formerly called gamma globulin, is a principal antibody in blood serum. A 0.470 g sample of immunoglobul
Nookie1986 [14]

The molecular mass of the immunoglobulin G, given the data from the question is 1.53×10⁵ g/mole

<h3>How to determine the molarity</h3>

We'll begin by calculating the molarity of the immunoglobulin G. This is illustrated below:

  • Volume = 0.106 L
  • Temperature (T) = 25 °C = 25 + 273 = 298 K
  • Osmotic pressure (π) = 0.733 mbar = 0.733 × 0.000987 = 0.00072 atm
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Van't Hoff factor (i) = 1
  • Molarity (M)

π = iMRT

M = π / iRT

M = 0.00072 / (1 × 0.0821 × 298)

M = 0.000029 M

<h3>How to determine the mole of immunoglobulin G</h3>
  • Molarity = 0.000029 M
  • Volume = 0.106 L
  • Mole =?

Mole = Molarity × volume

Mole = 0.000029 × 0.106

Mole = 3.074×10⁻⁶ mole

<h3>How to determine the molar mass of mmunoglobulin G</h3>
  • Mole = 3.074×10⁻⁶ mole
  • Mass = 0.470 g
  • Molar mass =?

Molar mass = mass / mole

Molar mass = 0.47 / 3.074×10⁻⁶

Molar mass = 1.53×10⁵ g/mole

Draw the product of nucleophilic substitution with each neutral nucleophile. When the initial substitution product can lose a pr
Margaret [11]

Answer:

Neutral nucleophile are: H2O, CH3OH, NH3, RNH2, R2NH, R3N, RCOOH, RSH and PR3. The products by nucleophilic substitution are diverse depending on the different nucleophiles, obtaining alcohol, eter, amines, ester and tioeter considering only the nucleophiles with a hydrogen available.

Explanation:

Please see the images attached.

Nucleophilic subtitution with water occurs under Sn1 mechanism. That's it because water as nucleophile is so weak.  With the other neutral nucleophiles, the reaction occur under Sn2 mechanism.

RSH + CH3I  -----> RSCH3  +  HI
