an unsaturated solution is made by completely dissolving 20.0 grams of NaNO3 in 100.0 grams of water at 20.0 degrees celcius. show a corrct numerical sat up for calculating the number of moles of nano3(gram-formula mass = 85.0 grams per mole) used to make this unsaturated solution.
Note the correct spelling of celsius.
Start sentences with a capital letter. Don't get lazy in chemistry and not use the shift key. nano3 isn't anything. Since you give the gram formula mass as 85.0 g/mol, I assume that is NaNO3.
20.0 g NaNO3 x (1 mol/85.0 g) = ? mols NaNO3.
