Ethanol is a common laboratory solvent and has a density of 0.789 g/mL. What is the mass, in grams, of 131 mL of ethanol?​

m=103g

Explanation:

Hello there!

In this case, according to the given information, it is possible for us to say that this problem is solved by considering the concept of density, as the degree of compactness of a substance and mathematically defined as the mass divided by the volume (d=m/V). In such a way, for this problem, we solve for the mass as follows:

m=d*V

And we plug in the density and volume to obtain:

m=0.789g/mL*131mL

m=103g
