The molar concentration of an HCl solution is 12.4 mol/L. How many moles of Hcl is in 1.50 L of HCl solution
1. Express 95 mg/l of Ca 2+ as milligrams per liter of CaCO 3 . 2. Express 221 mg/l of Ca(HCO 3 ) 2 as equivalents per liter of CaCO 3 . 3. Determine the concentration o
Which of the following sets of quantum number is not possible: (1) n=3, l=+2, m=0,and s = +1/2 (2) n=3, l=0, m=0,and s = -1/2 (3) n=3, l=0, m=-1,and s = +1/2
The known metal ion solution used contains 0.10 M of each of the six metal ions (i.e. 0.10 M Ag+ and 0.10M Pb2+). An equal volume of 3 M HCl and the known solution are mixed. What
