Answer to Question #120385 in General Chemistry for nian

Question

Ethanol is a common laboratory solvent and has a density of 0.789 g/mL. What is the mass, in grams, of 135 mL of ethanol?

Answer 1

Solution:

m=d*V - a mass of a substance

d=0.789 g/mL - the ethanol density.

V=135 mL - the volume of ethanol.

m=0.789g/mL*135mL=106.515g ~ 106.5g- the mass of ethanol.

Answer:

106.5g - the mass of ethanol.
