How will you prepare the following solutions from 6.0 M solutions of acetic acid and ammonia. Give exact details. Assume that a 10-mL graduated cylinder (in which volumes can be read to the nearest 0.1 mL) and a 100-mL graduated cylinder are available. a. 80 mL of 0.10 M HC2H3O2 b. 80 mL of 0.10 M NH3?
The water level in a graduated cylinder was at 211 rises initially it raised to 270 after adding a piece of lead is submerged. Determine the mass in grams of the lead?
