Answer:- Density is 2.54 gram per mL.

Solution:- $density=\frac{mass}{volume}$

Mass of the marble ball is given as 9.513 g and it's volume is 3.75 mL.

To calculate the density of the marble ball let's plug in the values in the formula:

$density=\frac{9.513g}{3.75mL}$

$density=2.54\frac{g}{mL}$

So, the density of the marble ball is 2.54 gram per mL.
