Answer:
Mass of benzene is: 149.3 g
Explanation:
Let's use density to calculate mass.
Density = Mass / Volume
Mass = Density . volume
Be careful, because density is in g/mL and the volume is in L. So let's convert the L to mL: 0.170 L . 1000 mL / 1L = 170 mL
0.8787 g/mL . 170 mL = Mass of benzene
Mass of benzene is: 149.3 g
Answer:

Answer:
This is a change in an objects motion caused by an unbalanced force.
- Acceleration
Answer:
Explanation:
In a saturated solution, more solute cannot be dissolved at a given temperature.
This is because, the solute dissolves in a solvent because of space between particles of solvent but on continuous addition of solute, the space between the solvent particles gets fulfilled. Thus no more solute particle can dissolve in a solvent.
