The solubility of Ba(NO₃)₂ is 130.5 g/L at 0ºC. How many moles of dissolved salt are present in 4.0 L of a saturated solution of Ba(NO₃)₂ at 0ºC

Question

Quizplus · Accepted Answer

The first step is to calculate the maximum amount (in moles) that can be dissolved in 1 liter of water at 0°C: 130.5 g/L x (1 mol / 259.55 g) = 0.5029 mol/L Then, we can calculate the maximum amount (in moles) that can be dissolved in 4.0 L of water: 0.5029 mol/L x 4.0 L = 2.0116 mol Therefore, the amount of dissolved salt in a saturated solution of Ba(NO₃)₂ at 0°C is 2.0 moles. So, the best choice is B) 2.0 moles.

The Solubility of Ba(NO3)2 Is 130

The Solubility of Ba(NO₃)₂ Is 130
