Here are 10 Ideal Gas Equation calculation questions using:

Pressure in mmHg or N/m² (Pa)
Temperature in °C or K
Volume in cm³

🔹 Useful Constants

$P V = n R T$ PV=nRT
$R = 8.314 J / m o l \cdot K$ R=8.314J/mol⋅K (when pressure is in Pa)
$R = 62.4 L \cdot m m H g / m o l \cdot K$ R=62.4L⋅mmHg/mol⋅K (when pressure is in mmHg)
$1 m^{3} = 10^{6} c m^{3}$ 1m3=106cm3
$K = ° C + 273$ K=°C+273
$1 a t m = 760 m m H g = 1.013 \times 10^{5} P a$ 1atm=760mmHg=1.013×105Pa

Good 👍 — you want Ideal Gas Equation calculations without giving moles, using:

Pressure in mmHg or N/m² (Pa)
Temperature in °C or K
Volume in cm³
Use combined gas law:

$\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2} V_{2}}{T_{2}}$ T1P1V1=T2P2V2

(Temperature must be in Kelvin)
