Answer: The mass will also be tripled.
Step-by-step explanation:
Density is defined as the mass contained per unit volume.
![Density=(mass)/(Volume)](https://img.qammunity.org/2019/formulas/chemistry/college/e60hk2z90fio2sd4f04ghqlwt6m3qfu0a7.png)
Density is characteristic of a substance and it remains constant at a particular temperature.
If volume increases/decreases then mass also increases/decreases proportionally. Hence density remains constant.
Thus when volume of the sample is tripled , the mass will also increase thrice or become tripled.
