How many ammonium ions and how many sulfate ions are present in an 0.260 mol sample of (nh4)2so4?
Anna11 [10]
The question requires that you assume complete ionization of the compound. This is:

(NH4)2 SO4 → 2 NH4 (+) + SO4 (2-)

Then, 1 mol of (NH4)2 SO4 produces 3 moles of ions: 2 moles of NH4 (+) and 1 mol of SO4 (2-)

=> 0.26 * 2 moles of NH4(+) = 0.52 moles of NH4 (+)

0.26 * 1 mol of SO4 (2-) = 0.26 moles of SO4 (2-).

Answer: 0.52 moles of ammonium ions and 0.26 moles of sulfate.ions.

The volume of a gas collected when the temperature is 11. 0°c and the pressure is 710 mm hg measures 14. 8 ml. What is the calcu
ivolga24 [154]

Answer:

Original: P₁ = 710 mmHg, V₁ = 14.8 mL, T₁ = (273.2 + 11.0) K = 284.2 K

New: P₂ = 370 mmHg, V₂ = ? mL, T₂ = (273.2 + 20.0) K = 293.2 K

Combined gas law: P₁V₁/T₁ = P₂V₂/T₂

Then, V₂ = V₁ × (P₁/P₂) × (T₂/T₁)

Calculated new volume, V₂ = (14.8 mL) × (710/370) × (293.2/284.2) = 29.3 mL
