Web11 apr. 2024 · Nitrogen (N) fertilizer application is one of the causes of soil acidification at tea plantations. However, the effect of N fertilizer application on the soil acidification characteristics of tea plantations with different acidities remains unclear. In this study, field experiments were conducted to investigate the effects of different nitrogen fertilizer … Web16 nov. 2024 · The number of mole of Na₂SO₄ required to prepare the solution is 0.322 mole . The Molality of a solution is defined as the mole of solute per Kg of water i.e. Molality = mole / mass (Kg) of water. With the above formula, we can obtain the mole of Na₂SO₄ in the solution as follow: Molality of Na₂SO₄ = 0.140 M. Mass of water = 2.30 Kg ...
