The two
Esters along with starting materials are shown below. The missing reagents ate shown in Blue encircled in red box. First reaction is carried out in acid which increases the reactivity of carboxylic acid (
electrophilicity odf carbonyl carbon). And second reaction is carried out in the presence of Base, which increases the
Nucleophilicity of nucleophile i.e. Alcohols.
Answer:
4 tabletes/dose
Explanation:
mass person = (90 Lb)×(Kg/2.20462 Lb) = 40.823 Kg body
amount of medicine = 50 mg/Kg body.day
frecuency = 2 dose/day
⇒ amount of medicine/day = (50 mg/kg body.day)×(40.823 Kg body) = 2041.168 mg/day
⇒ mg medicine/dose = (20141.168 mg/day)×(day/ 2 dose) = 1020.584 mg medicine/dose
∴ mg medicine/tablet = 250 mg medicine/tablet
⇒ # tabletes/dose = (1020.584 mg medicine/dose)×(tablet/250 mg medicine) = 4.082 tabletes/dose
⇒ # tabletes/dose ≅ 4 tabletes/dose

Below is the solution:
pOH = - log (5.75 × 10^−4) = 3.24
<span>pH = 14 - 3.24 = 10.76</span>
