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= \frac{mass}{volume} = \frac{49 g}{10 ml} = 4.9 g/ml
