Answer:
The density of the liquid is 4.9 g/ml
Explanation:
Density of a liquid is usually measured by filling a beaker of known weight and known capacity (total volume in ml you can fill it) and weighing it. The difference between the total weight (beaker+liquid) and the beaker weight is the liquid weight. Finally, you must divide <em>liquid weight/volume</em> to obtain density.
For the problem:
beaker=15 g
beaker+liquid=64 g
⇒liquid= 64 g - 15 g = 49 g
density= 
= 
= 4.9 g/ml
