Step-by-step explanation
Given:
Mass of flask when empty = 32.5g
volume of flask when empty = 125 ml
Mass of flask when complitely full = 143.5
Required: Density
Solution
Step 1: Find the volume and mass of the flask
Volume = 125 ml
Mass = 143.5 - 32.5 = 111 g
Step 2: Find the density
Density = mass/volume
Density = 111g/125ml
Density = 0.888 g/ml
Answer
Density = 0.888 g/ml
