Answer:
The answer to your question is: density = 0.993 g/ml
Explanation:
Data
mass beaker empty = 29.3 g
volume of liquid = 15 ml
mass beaker + liquid = 44.2 g
Formula
density = mass / volume
Process
mass of liquid = 44.2 - 29.3
= 14.9 g
density = 14.9 / 15
= 0.993 g/ml
The answer is b) 12 i believe
OPTION B & C are the answers....
