Example Calculation

Let’s walk through an example using the calculator:

  • Volume (V): 10 liters
  • Number of Moles (n): 2 moles
  • Temperature (T): 25°C

Step 1: Convert Temperature to KelvinT(K)=T(°C)+273.15=25+273.15=298.15 KT(K) = T(°C) + 273.15 = 25 + 273.15 = 298.15 \, KT(K)=T(°C)+273.15=25+273.15=298.15K

Step 2: Use Ideal Gas Law FormulaP=nRTV=2×0.0821×298.1510P = \frac{nRT}{V} = \frac{2 \times 0.0821 \times 298.15}{10}P=VnRT​=102×0.0821×298.15​

Step 3: Calculate PressureP=48.8810=4.89 atmP = \frac{48.88}{10} = 4.89 \, atmP=1048.88​=4.89atm

The calculator instantly shows 4.89 atm as the gas pressure.
