Submitting 2nd time as I was asked to resubmit to obtain help with the rest. Thank you.

Based on their molecular masses, match the correct molar mass with each molecule. CO Fe CO₂ Fe₂0₁ a C d 1 mol 55.85 g 1 mol 28.01 g 1 mol 44.01 g 1 mol 159.70 g

Predict the formula for each ionic compound. (Recall the polyatomic ions in the table below.) Some Common Polyatomic Ions Name Formula Acetate C2H3O2− Hydrogen carbonate HCO3− Hydroxide OH− Nitrate NO3− Carbonate CO32− Sulfate SO42− Phosphate PO43− Ammonium NH4+ Note: The names of positive polyatomic ions end in -ium. Many negative polyatomic ions have names ending in -ate. Another name for the hydrogen carbonate ion is bicarbonate.
