Question

calculate the volume of liquid with density5.45ml and mass 15ml

Answer 1

Answer:

The thing to remember about a substance's density is that it tells you the mass of every unit of volume of said substance.

In this case, the liquid is said to have a density of  

5.45 g mL

−

1

. The density is expressed in grams per milliliter, so right from the start, you can say that you know the mass of  

1 mL

of liquid.

More specifically, you can say that  

1 mL

of this liquid has a mass of  

5.45 g

.

All you have to do now is use the given density as a conversion factor to help you go from mass to volume

Explanation:

The answer is rounded to two sig figs, the number of sig figs you have for the mass of the liquid.
