Best ResponseYou've already chosen the best response.1Nitric acid is a strong acid so it fully dissociates into Nitrate and Hydrogen i.e. HNO3 > H+ + NO3 Secondly you need to use the formula: Molarity = Moles/Liters

Best ResponseYou've already chosen the best response.1NO, the volume has to be in L you have to convert the mL to L

Best ResponseYou've already chosen the best response.1so to convert: multiply 500mL by (1L/1000mL) note when you multiply mL cancels out and you are left with just liters

Best ResponseYou've already chosen the best response.00.60 because Molarity = moles of solute/Liters of solution (500.0 mL = 0.5 Liters) M = 0.30 moles HNO3/0.5 L = 0.60 M H + ions in solution

Best ResponseYou've already chosen the best response.0The concentration of the nitric acid solution is 0.60 M, and the nitric acid will dissociate completely to H+ (aq) and NO3 (aq). This means the hydrogen ion concentration is equal to the starting concentration of the acid.
