Natasha is learning about density in science class. She has been given three different geometric shapes made from different substances and asked to determine which has the greatest density. She measures the masses of the objects and records her results in the table below
What should Natasha do next to determine the relative densities of the objec
A. She should measure the temperature of each object.
B. She should measure the volume of each object.
C. She should measure the surface area of each object.

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
