Input Parameters

PV = nRT

Solve For:

Volume (L)

Moles (mol)

Temperature (K)

R = 0.08206 L·atm/(mol·K) | STP: 273.15 K, 1 atm, 22.4 L/mol

Quick Reference

Gas Constants

• R = 0.08206 L·atm/(mol·K)
• R = 8.314 J/(mol·K)
• R = 62.36 L·mmHg/(mol·K)
• STP: 273.15 K, 1 atm, 22.4 L/mol

Temperature Conversions

• K = °C + 273.15
• °C = K - 273.15
• °F = (9/5)°C + 32
• Always use Kelvin in gas law calculations!

💡 Key Relationships

• Boyle: P ↑ → V ↓ (inverse)
• Charles: T ↑ → V ↑ (direct)
• Gay-Lussac: T ↑ → P ↑ (direct)
• Avogadro: n ↑ → V ↑ (direct)
• Real gases deviate from ideal at high P, low T
