. 5point74 gm of a substance occupies a volume of
volume of 1.2 cm3 . Calculate its density with due regard for significant figures.
A: 4.8 g/cm3
B: 2.3 g/cm3
C: 2.4 g/cm3
D: 3.8 g/cm3
As voulme has least two significant figures so the answer must be expressed in two singnificant figures.
Thus density will be 4.8 g/cm3.
Hence, the correct option is (A) i.e. 4.8 g/cm3
