How much higher in energy (Kcals/mol) is conformation B than conformation A?

The following evidence was obtained from an experiment to determine the molar concentration of a sodium nitrate solution. A sample of sodium nitrate solution was evaporated to dryness and the mass of solid residue was measured.Evidence:Volume of solution = 10.00 mLMass of beaker = 79.54 gMass of beaker and residue = 82.96 gFrom this data, calculate the molar concentration of the original sodium nitrate solution. Record only your numerical answer with the correct number of significant digits.  You do not need to include units as the units appear for you beside the answer box already.

Masses :  Ca = 40.08 g   S= 32.07 g  O= 16.00 g  A 35.0 mL sample of CaSO4 was evaporated to dryness, leaving 0.967 g of residue. What was the molarity of the original solution?   step by step please
