Answer:
106 mL
Explanation:
In order to be able to answer this question, you must understand what the density of a substance tells you.
The density of a substance is nothing more than the mass of that substance that occupies one unit of volume.
In your case, the density of ethanol is given in Grams per milliliter, which means that one unit of volume will be
1 mL
.
So, ethanol has a density of
0.785 g mL
−
1
, which is equivalent to saying that if you take exactly
1 mL
of ethanol and weigh it, you will end up with a mass of
0.785 g
.
Now, you know that the volume you're using has a mass of
83.3 g
. Well, if you get
0.785 g
for every
1 mL
of ethanol, it follows that this much mass will correspond to a volume of
83.3
g ethanol
⋅
ethanol's density
1 mL
0.785
g ethanol
=
106.11 mL
Rounded to three sig figs, the answer will be
V
ethanol
=
106 mL

Answer:
V₂= 33581.4 ft³
Explanation:
Given data:
Initial temperature = -15 °C (-15+273 = 258 k)
Initial volume = 28500 ft³
Final temperature = 31 °C (31+273 = 304)
Final volume = ?
Solution:
According to the Charles's law
Temperature and volume are directly related to each other.
V₁/T₁ = V₂/T₂
V₂ = V₁×T₂ /T₁
V₂ = 28500 ft³ × 304 k / 258 k
V₂ = 8664000 ft³.k/ 258 k
V₂= 33581.4 ft³
