Molarity calculations
calculate the molarities of the following solutions:
2.3 moles of sodium chloride in 0.45 liters of solution.

An electrons position cannot be known precisely only it's probability of being in a certain location can be known

How might this scientific phenomena be explained? a paper clip floats on water.

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
