C7H6O3 + C4H6O3 → C9H8O4 + C2H4O2
Convert the 100g of salicylic acid (SA) into moles and the ratio is 1:1.
Convert moles of aspirin into grams of aspirin where grams = molar mass *moles which is the theoretical yield.Percentage yield =50g (actual yield)* 100

Answer:
ΔG°rxn = -15,1 kJ/mol
Explanation:
ΔG°rxn = -RTlnK = -(8.314 J/mol K)(298 K)×ln436
ΔG°rxn = -1.51×10^4 J/mol = -15.1 kJ/mol
an exergonic reaction, it makes sense, since K > 1
Answer:
88.614 gm/mol
Explanation:
amount of charge passed through the cell
= 150.1×10^-3 A×17.42 min× 60 = 156.88C = 156.88/96500 C/F
=1.62×10^-3 F
molar mass of the metal = 0.1641 gm/3mole metal/F × 1.62×10^-3 F =88.614 gm/mol
