You prepare an NaOH solution with a concentration of approximately 0.200 M. In order to standardize the solution, you will need to titrate it against an acid standard. What mass of sulfamic acid (H2NSO3H) will you need to use in order that the titration will require 40.00 mL of the NaOH solution?
A 10.0 ml sample of aqueous HCl requires 18.66 ml of 0.206M NaOH to reach the endpoint . What is the molar concentration of HCl ? The chemical equation of the reaction is
the MWP for a tank is 207.0 bar at 20 degrees C. If the tank is filled at 200.0 bar at 20 degrees C, what is the maximum pressure the tank achieves if left in the sun on a boat, if the tank temperature reaches 35.0 degrees C?
