volume = final volume of water - initial volume of water
volume = 125 ml - 100 ml = 25 ml
From the question we have
![density = (125)/(25) = 5 \\](https://img.qammunity.org/2022/formulas/chemistry/college/g1nnauz21ongqhz6cmawa8x7e4b3t5e3t3.png)
We have the the final answer as
5 g/mL
Hope this helps you
