The solubility of sodium nitrate at 40C is 104g/100g of water. (a) how much sodium nitrate will be obtained if 25.5g of saturated solution at 40C is evaporated to dryness?
(b) what is the maximum amount of solid that can be dissolved in 250g of water at 40C?

I’ll give you brainliest if with proper explanation. Pls help

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
