The formula of the volume for a cylinder is pi*r^2*h. Given the diameter of 1 inch and height/length of 2.5 inches, the volume is calculated by:
V = pi*(0.5^2)*2.5 = 1.9625 in^3
the cork density is 0.26 g/mL, since the units of the volume is in^3, convert to cm^3 or mL:
1.9625 in^3 * (2.54cm/1in)^3 = 32.16 cm^3
So, the mass of the cylindrical cork is 0.26 g/mL * 32.16 cm^3 = 8.36 g

We are given with the titration with <span> 0.100 M NaOH obtained at 15.00 mL. The moles equivalent of HCl here is equal to 0.1*15x10^-3 or 0.0015 moles. This is equivalent to 0.055 grams HCl. the percent purity then is equal to 0.055/0.5725 or 9.55%.</span>
