Answer:

Because density is mass divided by volume and it will always stay the same for a certain substance while mass and volume will always vary.

Density classifies as a characteristic explicitly and volume does not. For something to have a characteristic, this means that it is something used to show what exactly that something is. For example, you can have 3 lead blocks of different sizes but they all have the same substance which is lead. The density will all be the same for all 3 blocks, but the volume is different for each object, meaning that the size of the object is different. Hope this helps!

How many gallons of gasoline that is 5% ethanol must be added to 2,000 gallons of gasoline with no ethanol to get a mixture that

Amanda [17]

Answer:

$V_1= 3000 gal$

Explanation:

We have 3 solutions:

Solution 1 (with ethanol)
Solution 2 (no ethanol)
Final solution

$V_f=V_1 + V_2$

and for the ethanol:

$V_f*0.03=V_1*0.05 + V_2*0$

$V_f=V_1 \frac{5}{3}$

Combining:

$V_1 \frac{5}{3}=V_1 + V_2$

$V_1 \frac{2}{3}= V_2$

$V_1= \frac{3}{2} V_2$

If V2=2000 gal:

$V_1= \frac{3}{2} 2000 gal$

$V_1= 3000 gal$
