A 2.16 g of a substance occupies 1.5 cm3. Its density to appropriate significant figure is:
Step 1 : Given data
Mass of substance =
Volume =
Step 2 : Formula used
Density =
Step 2: Evaluating density
Putting values in above formula , density =
Since There aresignificant figures in measured mass
Whereas there are only significant figures in measured volume.
Hence density should be expressed to only significant figures i.e
