Calculate the %(m/v) of hydrochloric acid using the molar concentration you found. Shows calculations. Records final answer to correct significant digits. Records the concentration with the appropriate units. The molar concentration I found was 0.1M.

Please answer the question! Find the molarity and mass percent of ammonium hydroxide solutions. Thanks!

Hello sir, I just want a solution without explanations and a clear line

Calculate H30" of the following polyprotic acid solution: 0.130 M H2CO3 (Kal 4.3 × 10-7, K2 = 5.6 x 10 11). Express your answer using two significant figures. [H3O*] = M

Each value represents a different aqueous solution at 25 °C. Classify each solution as acidic, basic, or neutral. Acidic Basic Neutral Answer Bank H*] = 2.7 x 10-9 РОН — 4.40 OH| = 4.8 × 109 =D4,8 x РОН 3 13.51 |H*| = 1.0 x 10-7 pH = 5.58 pH = 11.02 H* = 2.9 x 10 %3D pOH = 7.00 OH| = 4.5 x 10-
