Answer:
3
Explanation:
In scientific notation, the number of integers in the first part will always be the amount of significant figures.
For example,
1) 1.542505 x 10^17 =7 significant figures
1) 1.54 x 10^17 =3 significant figures
Mass of medicinal agent taken = 1.2 g
the volume is 60 mL
Specific gravity = 1.20
So the mass of solution = specific gravity X volume = 1.20 * 60 = 72g
Now if we have increased the volume by 0.2 so the new volume = 60.2
New mass = 72 + 1.2 = 73.2
Specific gravity = mass / volume = 73.2 / 60.2 = 1.22 g/mL
