Help ASAP I’ll mark you as brainlister:((?!!

Answer:
Explanation:
pressure(volume)=Number of moles(constant)(tempature)
(88.4 kPa) (344 mL) =N(0.0821)(85C)
all you need to do from here is convert to SI units (kelvin, liter, pascal) and solve for n
if you leave it as it you get N=4357.61266
converting it gives a number a little closer to N=0.01024061 (used a ideal gas law calculator to doble check the math lol)
Hope this helps!!
