Answer:
(b) Water
Explanation:
The density of the liquid is found by dividing its mass by its volume.
__
<h3>mass</h3>
The mass of the liquid is the difference in mass between the full and empty graduated cylinder:
liquid mass = (145 g) -(45 g) = 100 g
<h3>volume</h3>
The cylinder is said to contain 100 mL of the liquid, so that is the volume of interest.
<h3>density</h3>
The ratio of mass to volume is the liquid's density:
ρ = (100 g)/(100 mL) = 1 g/mL
This density identifies the most likely liquid as water.
