I have a very lucrative offer for you if you answer the questions: The volume of a 67.2-gram sample of platinum with a density of 21.5 g/cm3 is

The diagram below represents information that can be found on the periodic table for the element argon. The mass number for an argon isotope is represented at: (graph is attached)

The sum of the atomic mass values of the atoms in a chemical formula is known as the

Using the table for reference, find the formula mass for nitric acid, HNO3. (table is attached)

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
