Dear sir /ma'am, The solubility of sodium fluoride, NaF, in water at 25 degree Celsius is 4.100g per 100.0g of water. Assume 100.0g of water occupies a volume of 100.0ml.A saturated solution is prepared by adding 6.000gof NaF to 100.0ml of water at 25 degree Celsius in a beaker and steering thoroughly. The following sequence of steps is carried out : Step 1:50.0ml of solution is removed from the beaker and discarded. Step 2:50.0ml of water is added to the beaker and steered. Step 3:50.0ml of solution is Removed from the beaker and discarded. The maximum mass of NaF now remaining and recoverable from the beaker is? Options: A) 1.025g B) 1.900g C) 1.975g D) 4.100g Please help me to solve it. |
