3.20 × 105 gallons of tar (SG = 1.20) is stored in a 20.0-ft tall storage tank. What is the total mass of the liquid in the tank

lilavasa [31]

Answer:

Mass of the liquid in the tank will be $1.45\times 10^8kg$

Step-by-step explanation:

We have given volume of tar $V=3.20\times 10^5gallon$

1 gallon = 3.785 liter

So $3.20\times 10^5gallon=3.20\times 10^{5}\times 3.785=12.112\times 10^5liter$

Specific gravity = 1.2

Density of water $=1000kg/m^3$

We know that specific gravity $=\frac{density\ of\ liquid}{density\ of\ water}$

$1.2=\frac{density\ of\ liquid}{density\ of\ water}$

Density of liquid $=1200kg/m^3$

So mass of liquid = volume × density

= $12.112\times 10^5\times 1200=1.45\times 10^8kg$

So mass of the liquid in the tank will be $1.45\times 10^8kg$

the temperature in an experiment is increased at a constant rate over a period of time until the temperature reaches 0 degrees c

dsp73

Answer:

x = 28 (So it takes 28 hours for the temperature to reach 0°C.)

y = -70 (So the temperature when the experiment begins is −70°C.)

Step-by-step explanation:

To find the the x value, you remove the y value or replace it with 0.

0 = 5/2x - 70

Next you move the variable.

70 (2/5) = x (multiply 70 by 2 to get 140 and divide that by 5)

And now you simplify to get:

To find the y value, you remove the x value or replace it with 0.

y = 0 - 70

And now you simplify to get:

-70

x = 28

y = -70
