    Heya!!!!!!!!!! Solution : first convert these terms to suitable unit so, ⛔V = 400cm^3 => 400 × 10^-3 => 0.4 L ⛔ ⛔P = 760mmhg = 1 atm ⛔ ⛔ R = 0.08 atm L / mol K ⛔ ⛔T = 300 K ⛔ simple, ideal gas equation ⭐ PV = nRT ⭐ ?⏩ 1 X 0.4 = n X 0.08 X 300 ⏩⏩⏩ n = 0.0167 moles⏪⏪ ⏪ we convert all these digits kunki humko jo bhi unit leni hai bo R constant ke according leni hai ye thee important baat aur padhai badhai kaise chal rahe hai ❌❌❌❌❌❌ jai bajarang bali ❌❌❌❌❌❌
