Question

Please help meee! Chemistry!

Answer 1

P=18000000/6 zeros. not sure how to do rest

Answer 2

Explanation:

a) $n = \dfrac{PV}{RT} = \dfrac{(1.8×10^7\:\text{Pa})(3\:\text{L})}{(8310\:\text{L•Pa/mol•K})(300\:\text{K})}$

$\:\:\:\:\:\:\:= 21.7\:\text{mol}$

b) $P = \dfrac{nRT}{V}$

$\:\:\:\:\:\:\:\:\:= \dfrac{(50\:\text{mol})(8310\:\text{L•Pa/mol•K})(300\:K)}{(3\:L)}$

$\:\:\:\:\:\:\:\:\:=4.2×10^7\:\text{Pa}$
