Can someone PLEASE help me with a few Chemistry questions?

OpenStudy (zale101):

Subtract after evaporation and before evaporation to get the actual grams of NaCl alone without the mass of dish.

OpenStudy (vera_ewing):

Does knowing the ratio of masses of the elements in a compound lead to the unique chemical identity of the compound?

OpenStudy (zale101):

Then divide the grams that you'll get after subtraction by the molar mass of NaCl, and multiply by 100% to get the percentage of NaCl

OpenStudy (zale101):

First, work on the previous question instead of deleting it.

OpenStudy (vera_ewing):

@Zale101 I need help with that question ^
