Dear mate,
Kindly mark the answer as brainliest if you find it useful.
Here's what you were looking for:
The given mass is 4.237 g. It has three points after decimal but the volume which is 2.5cm3 has only one point after decimal. ( All the values in a question must be the same precise as the least precise value)
So round off the mass to one decimal place. Therefore the new mass is 4.2 g.
Now use Density=Mass/Volume
Therefore,
Density=4.2/2.5= 1.68g/cm3
Hope this clears your doubt.✌
