Answer : The concentration of the is, 0.115 M
Explanation :
Using dilution law,
where,
= basicity of an acid = 1
= acidity of a base = 1
= concentration of = 0.125 M
= concentration of KOH = ?
= volume of = 25 ml
= volume of NaOH = 27.07 ml
Now put all the given values in the above law, we get the concentration of the .
Therefore, the concentration of the is, 0.115 M
Answer:
48.03grams
Explanation:
Density of a substance is calculated as follows:
Density (g/cm³) = mass (g) / volume (cm³)
Based on the information given in this particular question:
Density of lead (Pb) = 11.3 g/cm³
Volume of lead (Pb) = 4.25 cm³
Density = m/V
11.3 = mass/4.25
Mass = 48.025
= 48.03grams.
