Answer:
Correct option is
A
3.3
Mass of the substance m=49.53g
Volume of the substance V=1.5cm
3
Density of the substance d=
V
m
∴ d=
1.5
49.53
=33.02gcm
−3
As 49.53 has four significant figures whereas 1.5 has two significant figures.
Thus, the value of the density of the substance must have two significant figures.
Thus, the density of the substance d=3.3gcm
−3
