Answer 2

\[\huge\rm \frac{ P_1V_1 }{ T_1 }=\frac{P_2V_2}{T_2}\]
\[\rm P_1 =1.5 ~atm ~~,~~~~~V_2=1.0~L~~~,~~~~~~T_1=273 K\]\[\rm P_2 =?(find) ~~,~~~~~V_2=5.0~L~~~,~~~~~~T_1=298 K\]
plugin the values, solve for for P_2

Answer 3

use ideal gas law for the 3rd one \[\large\rm PV=nRT\]
R is constant \[\large\rm R=8.31 \frac{KPa \cdot L}{mole\cdot K}\]
