The ideal gas law states that the volume, v, of a gas in liters varies directly with the amount of the gas in moles, n, and the absolute temperature in kelvin, t, and varies inversely with the pressure, p, of the gas. two moles of a gas has a volume of 35.424 l at 270 kelvin when p = 1.25 atm. what is the volume of 3 moles of a gas at 280 kelvin when p = 1.5 atm?
a. 11.48 l
b. 27.33 l
c. 45.92 l
d. 103.32 l

It is stated that:

So, we will have  the formula V=nRT/P

V= nRT/P

 = (3mol) (0.082057 Latm/Kmol)(280K)

                      1.5

= 45.9536L

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
