Answer:
<h3>The answer is 41.05 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual density = 0.95 g/mL
error = 0.95 - 0.56 = 0.39
So we have
We have the final answer as
<h3>41.05 %</h3>
Hope this helps you
Converts the 25 lb to kg
multiply the kilograms by the dose (10 mg/kg)
multiply the amount of ibuprofen by the conversion factor of the concentration of the suspension to calculate the mL
25 lb x 0.453592 kg/1lb= "A kg"
A kg x 10 mg/kg = B mg
B mg x 5.0 mL/ 100 mg = "C mL of suspension"

Answer:
1.23x10^-6 mole
Explanation:
A clear understanding of Avogadro's hypothesis proved that 1mole of any substance contains 6.02x10^23 atoms. This indicates that 1mole of Ag contains 6.02x10^23 atoms.
Now, 1f 1mole of Ag contains 6.02x10^23 atoms, then Xmol of Ag will contain 7.41x10^17 atoms i.e
Xmol of Ag = 7.41x10^17/6.02x10^23 = 1.23x10^-6 mole
