Determine the mass [kg] of the compressed air in a scuba diving tank given the following information. the internal volume of the tank is 10 liters [l] and the absolute pressure inside the tank is 20.8 mega pascal [mpa]. the temperature of the air inside the tank is 20 degrees celsius [oc]. use the ideal gas law to solve for the mass. the ideal gas law is given by:

m=2473.5 kg

use pv=mrt idea gas equation

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

i believe the answer is a
