Question

To make a saturated solution, 36 g of sodium chloride is dissolved in 100 g of water at 293 kelvin . find its concentration at this temperature.

Answer 1

Answer:. 6.15 mol/liter

Explanation:for 1M solution we need 58.5 gram ( mol. weight of NaCl) in 1000 gram (1 liter ) water

W=ENV/1000

N = Wx1000/ ExV

N= 36 x1000/ (58.5x100)

N= 6.15

concentration = 6.15 mol/liter
