Molar concentration calculation with absolute uncertainty


A solution of FX is prepared by dissolving (0.0933±0.0004) g of NaF (M=(41.989±0.001) g/mol) in 156.00± mL of water. Calculate the concentration of FX in the solution and its absolute uncertainty.


First of all, uncertainty aside, I got 0.0141 for the concentration of FX. However, this is not the correct answer (according to Sapling Learning).


Furthermore, what technique should I use to find the absolute uncertainty?
