Ethanol is a common laboratory solvent and has a density of 0.789 g/mL. What is the mass, in grams, of 113 mL of ethanol?

Respuesta :

 D = m/V 
0.789 = m/111 
m = 87.579g

Answer: The mass of ethanol is 89.2 grams

Explanation:

Density is defined as the mass contained per unit volume.

[tex]Density=\frac{mass}{Volume}[/tex]

Given : Mass of ethanol =  ?

Volume of ethanol = 113 ml

Density of ethanol = 0.789 g/ml

Putting in the values we get:

[tex]0.789g/ml=\frac{mass}{113ml}[/tex]

[tex]mass=89.2g[/tex]

Thus mass of ethanol is 89.2 grams
