Answer : The mass of sample is, 267.5 grams.

Explanation :

Density : It is defined as the mass of a substance contained per unit volume.

Formula used :

$Density=\frac{Mass}{Volume}$

Given:

Volume of Pb = $23.57cm^3$

Density of Pb = $11.35g/cm^3$

Now put all the given values in the above formula, we get the mass of Pb.

$11.35g/cm^3=\frac{Mass}{23.57cm^3}$

$Mass=267.5195g=267.5g$

Therefore, the mass of sample is, 267.5 grams.
