1) What is the molarity of the solution if you have 1.5 L of solution that contains 2.7 mol of CaCl2 ?

2)You dissolve 4.5 g of NaCl in water, for a total solution volume of 2 L. What is the molarity of the solution? The molar mass of NaCl is 58.44 g/mol. using dimensional analysis

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )

At element makes up all organic compounds?

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
