How many moles of air are there in a 125 mL flask if the pressure is 739 torr and the temperature is 18°C?
Answer:
pV = nRT
T= 18 degree Celsius = 291.15 kelvin
p= 739 torr = 0.97236856 atmospheres
R= 0.082
V= 0.125
therefore n= 0.0051 moles (to 2 sig figures)
pV=nRT
p=pressure
V=volume
n=moles
R=constant
T=temperature
man do your homework
i'm not sure about moles but there would be 12 badgers and 1 aardvark
not sure.
