A beaker contains 203 mL of a 6.67 M HCl(aq) solution. Determine the new concentration of the solution after it is diluted by adding 159 mL of water.
7. 2.00 moles of an ideal gas at 20.0 degrees C expands isothermally from an initial volume of 20.0 L to a final volume of 40.0 L. Calculate the work, w, for this process (a) for expansion against constant pressure of 105 Pa, and (b) if the expans..
Given the formula M1V1=M2V2 1.)What is the final volume in milliliters when 0.850L of a 21.5M solution is diluted to 14.5M ? 2.) A 856mL \rm NaCl solution is diluted to a volume of 1.02L and a concentration of 6.00\it M . What was the initial conc..
