Calculate the Molarity of the unknown acid if 25.0 mL of the acid reacts with 17.50 mL of 0.14 M NaOH solution. Assume that NaOH and acid react in 1:! ratio. Show your work. (Hint: Find the moles of NaOH from the given molarity and volume. mols of NaOH = mols of acid. Knowing ...
Calculate the mass of KHP (molar mass 204.44 g/mol) that reacts with 15.0 mL of the 0.15 M NaOH solution (molar mass 40.00 g/mol) required for standardization of the NaOH solution. Show your work.
sorry i don't know
A puck of mass m = 1.5 kg slides in a circle of radius r = 20 cm on a frictionless table while attached to a hanging cylinder of mass M = 2.5 kg by a cord through a hole in the table. What is the speed of mass m that keeps the cylinder at rest?
