Answer
a. $0.24\text{ mols}$
b. $0.48\text{ mols}$
c. $0.11\text{ mols}$
Work Step by Step
a.
$n=\frac{PV}{RT}$
$n=\frac{1.00*6.0}{0.08206*298}=0.24\text{ mols}$
b.
$n=\frac{PV}{RT}$
$n=\frac{1.97*6.0}{0.08206*298}=0.48\text{ mols}$
c.
$n=\frac{PV}{RT}$
$n=\frac{0.296*6.0}{0.08206*200}=0.11\text{ mols}$
