The full reaction mechanism of step 1 was obtained from Bartleby and attached to this answer. The steps involved in the reaction are:
1) Loss of Br- and formation of a carbocation
2) Attack of CH3CN on the carbocation
4) Formation of a quaternary nitrogen intermediate
5) Attack of water on the quaternary nitrogen intermediate
6) Loss of the water molecule
5) Formation of the amide product
b)
i) sodium hydroxide
ii) HCl
Hey there!
Sucrose is C₁₂H₂₂O₁₁.
Find molar mass of sucrose:
C: 12 x 12.01 = 144.12
H: 22 x 1.008 = 22.176
O: 16 x 11 = 176
--------------------------------
342.296 grams
That is the mass of one mole of sucrose.
We have 0.0287.
342.296 x 0.0287 = 9.82
The mass of 0.0287 moles of sucrose is 9.82 grams.
Hope this helps!

Given information:
Mass of pure silver = 195 mg
To determine :
Mass of silver chloride required to plate 195 mg of pure silver
Calculation:
The silver chloride used for silver plating usually contains 75.27 % silver
i.e.
every 100 mg of silver chloride will contain 75.27 mg silver
therefore, amount of silver chloride corresponding to 195 mg of silver would be = 195 mg * 100 mg/75.27 mg
= 259.1 mg
