Question

What mass of sodium chloride would be needed to make a saturated solution in 10g of water at 293K

Answer 1

36 gram of sodium chloride is dissolved in 100 g water at 293 K to make a saturated solution. Therefore,
mass of solution = 100 + 36 =136 g
So, amount of sodium chloride needed to make a saturated solution of 10 g = (36/136) x 10
  = 2.65 g
