Answer:
240 mg
Explanation:
In a dilution, the total quantity of the solute remains equal, so the concentration multiplied by the volume, or mass, of it, must be constant. In this case, the concentration is measured by the mass (w/w), so:
C1M1 = C2M2
Where C is the concentration, M is the mass, 1 is the concentrated solution, and 2 the diluted. The powder mupirocin has 100% of concentration, and the diluted solution will be mass equal to 22 g plus the mass added, so:
100%*M1 = 3%*(22 + M1)
100M1 = 66 + 3M1
97M1 = 66
M1 = 0.6804 g
But the ointment already has 2% of mupirocin, which is in mass:
0.02* 22 = 0.44 g
So, the mass needed to be added is 0.6804 - 0.44 = 0.24 g = 240 mg

Answer:
The potential wrt. calomel is 1.254 V
Explanation:
Given:
Potential wrt. silver chloride
V
Potential wrt. saturated silver chloride
V
Potential wrt. SCE
V
Now potential wrt. hydrogen is given by,
V
And we find for potential wrt. calomel,
potential wrt. hydrogen + potential wrt. SEC

V
Therefore, the potential wrt. calomel is 1.254 V
