Question

How much carbon dioxide is there in a 3.4L balloon at SATP

Answer 1

Standard Ambient Temperature and Pressure (SATP):

$T = 298.15 \;K \\ p = 1\; bar =0.986923 \;atm$

Ideal Gas Law

pV=nRT

R = 0.08206 L×atm/mol×K

$n= \frac{pV}{RT} \\ n(CO_2) = \frac{0.986923 \times 3.4}{0.08206 \times 298.15}= 0.137 \;mol$

Answer: 0.137 mol
