Answer:- Density is 2.54 gram per mL.
Solution:-
![density=(mass)/(volume)](https://img.qammunity.org/2019/formulas/chemistry/middle-school/58e864b2s1n4rc7orx1hyjc14q5gekqjio.png)
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=(9.513g)/(3.75mL)](https://img.qammunity.org/2019/formulas/chemistry/middle-school/yfwnbbtqsk9kenvqoatqi9n1e7w1a4es04.png)
![density=2.54(g)/(mL)](https://img.qammunity.org/2019/formulas/chemistry/middle-school/f4np85lrrdxlbc1iznwyzewlwh9uuywlbf.png)
So, the density of the marble ball is 2.54 gram per mL.
