Final answer:
The mass of the silver sample is approximately 136.71 g.
Step-by-step explanation:
To find the mass of the sample, you can use the formula mass = density x volume. In this case, the density of silver is given as 10.49 g/cm³ and the volume is given as 12.993 cm³. Plugging these values into the formula, you get mass = 10.49 g/cm³ x 12.993 cm³ = 136.70657 g.
Therefore, the mass of the silver sample is approximately 136.71 g.
