Answer to Question #121210 in General Chemistry for Anna

Question

Find the final volume of a gas sample (5 mol) at 1720 mmHg and 64°C of the gas is added, temperature drops to 10 °C and the pressure increases to 1900 mmHg .

Answer 1

(P₁V₁) / (T₁) = ( P₂ V₂) / (T₂ )

(1720) (5) / (337) = ( 1900) (V₂ )/(283)

V₂ = ( 283)(1720)(5) / (337)(1900)

V₂ = (2433800) / (640300)

V₂ = 3.8 mol
