מחשבון חוק הגז האידיאלי

PV = nRT — פתרון לכל משתנה חסר.

מבוא

Ideal Gas Law Calculator — PV = nRT — solve for any missing variable. Enter Pressure P (atm) — blank if unknown, Volume V (L) — blank if unknown, Moles n — blank if unknown, Temperature T (K) — blank if unknown to get an instant, accurate result.

נוסחה

Ideal gas law: PV = nRT, with R = 0.0821 L·atm/(mol·K). Enter any three of P, V, n, T to solve for the fourth.

צעד אחר צעד

  1. Enter the Pressure P (atm) — blank if unknown.
  2. Enter the Volume V (L) — blank if unknown.
  3. Enter the Moles n — blank if unknown.
  4. Enter the Temperature T (K) — blank if unknown.
  5. Click Calculate to see your result instantly.

דוגמה מהעולם האמיתי

Example: With Pressure P (atm) — blank if unknown = 1, Volume V (L) — blank if unknown = 22.4, Moles n — blank if unknown = 1, the Ideal Gas Law Calculator gives Unknown: T, Value: 272.9798.

שאלות נפוצות
