Calculate the number of HCl moles in 6.50 mL of 12M HCl solution
1) what volume (in mL) of a 12.0M HCl (aq) solution contains 0.600 moles of HCl? 2) "concentrated" hydrochloric acid has a concentration of 12M. How many moles HCl are in 25 mL of conc. HCl?
Calculate the number of moles of HCl contained in the two volumes of HCl solution (25.0ml and 50.0mL: remember to use the molarity of the solution rather than the molar mass of HCl to find molarity).
Calculate the concentration of HCl in the 250.0 mL volumetric flask and calculate the excess number of moles and total number of moles of HCl added to the alkali metal carbonate. From the total number of moles of HCl added and knowing the excess number of moles, calculate the moles of HCl that reacted with M2CO3. Use the following data for the calculations: mass of m2co3 transferred = 0.3877 g volume of 1mol HCl added to alkali metal = 20...
