nekit [7.7K]

Answer: 22368.4 Liters

Explanation:

Initial Volume of gas V1 = 20000 liters

Initial pressure of gas P1 = 850 torr

Final volume V2 = ?

Final (standard) pressure P2 = 760 torr

Apply the formula for Boyle's law:

P1V1 = P2V2

850torr x 20000L = 760torr x V2

V2 = (850torr x 20000L)/ 760torr

V2 = (17000000)/760torr

V2 = 22368.4L

Thus, the volume of the gas at standard pressure is 22368.4 Liters

Needed help plzzz on this chemistry homework.

Hertz is units for frequency. (waves per second)
wavelength = speed/frequency

if you're given the speed use that to calculate, if not then you can probably assume it's a wave of light and use the speed of light (3x10^8 m/s) to calculate.

wavelength = (3x10^8)/(1.28x10^17)
= 0.000000002 m
= 2.34 nm
