Answer:
2) solution
mass = 750 gm
volume = 62.5 cm^3
density =?
density = mass / volume
= 750 / 62.5
=12 g/cm^3
Explanation:
3) solution
Volume 1 =50 ml
Volume 2= 70 ml
Volume = Volume 2 - Volume 1
= 70-50
= 20 ml
1ml = 1 cm^3
20ml = 20 cm^3
mass = 60gm
volume = 20cm^3
density = mass/volume
= 60/ 20
= 3 gm/cm^3
