Explanation:
Answer:
1. molarity is = 0.1174
2. molarity is = 9.3
3. molarity is =0.009392
Explanation:
Q#1.
mass of sucrose is 14.07g
molar mass of sucrose is 342 3g/mol
so, 14.07x1/342.3 = 0.0411
now the volume is of water is 0.35
so, 0.0411/0.35 = 0.1174
Q#2.
concentration is 4.5
so, 4.5x1/1000= 0.0045
then, 0.0411/0.0045 = 9.13
Q#3.
M1M1=M2M2
molarity of the same sucrose is 0.1174
so, diluted in 40mL
and the volumetric flask is 500mL
so, 0.1174x40/500= 0.009392
Answer:
Option B, aspirin’s ester group provides greater digestibility to aspirin
Explanation:
Aspirin ester group has three parts
- carboxylic acid functional group (R-COOH)
- ester functional group (R-O-CO-R')
- aromatic group (benzene ring)
Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -
aspirin
(acetylsalicylic acid) + water → salicylic acid + acetic acid
(ethanoic acid)
Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.
