WebPROBLEM 3.4. 14. The following ionic compounds are found in common household products. Write the formulas for each compound: (a) potassium phosphate. (b) copper (II) sulfate. (c) calcium chloride. (d) titanium dioxide. (e) ammonium nitrate. (f) sodium bisulfate (the common name for sodium hydrogen sulfate) WebThe mass (in grams) of a compound is equal to its molarity (in moles) multiply its molar mass: grams = mole × molar mass. E.g. Molar mass of NaCl is 58.443, how many grams is 5 mole NaCl? grams = 58.443 × 5 = 292.215 (g) Molar mass of AgNO3 is 169.873, 2 kg AgNO3 is equal to how many moles?
