<u>We are given:</u>
The force applied on the poor hamster (F) = 12 N
Acceleration of the poor Hamster (a) = 8 m/s²
<u>Solving for the mass of the Poor Hamster:</u>
From newton's second equation of motion, we know that:
F = ma
<em>replacing the given values</em>
12 = 8 * m
m = 12/8 kg
m = 3/2 kg
The poor Hamster weighs 3/2 kg
Ibuprofen is synthesized by reacting ethyl 2-(4-isobutylphenyl)acetate with base, the base abstracts the acidic proton and enolate is formed which on reaction with diethyl carbonate generates diethyl 2-(4-isobutylphenyl)malonate
(A). diethyl 2-(4-isobutylphenyl)malonate on treatment with Base again looses the acidic proton and forms enolate. The enolate with treatment with Methyl Iodide yields diethyl 2-(4-isobutylphenyl)-2-methylmalonate
(B). diethyl 2-(4-isobutylphenyl)-2-methylmalonate on
hydrolysis give
Ibuprofen.
Answer: Heat required for 17.3 g of water to completely melt will be 5.785 kJ.
Explanation: Heat of fusion is defined as the amount of heat require to change the state from solid to liquid for 1 mole of solid at its melting point. It is expressed as 
We are given 17.3 grams of water. So, to convert it into moles, we use the formula:

Molar mass of water = 18g/mol
Putting values in above equation, we get:

Moles of water = 0.961 moles
For 1 mole of water, heat of fusion is 6.02kJ/mol
So, for 0.961 moles of water, heat of fusion will be = (0.961 moles × 6.02 kJ/mol) = 5.785 kJ
