What is the molarity of a solution of HCl if 5.00 mL of the HCl solution is
titrated with 28.6 mL of a 0.145 M NaOH solution?

Round your answer to 3
decimal places.

HCl + NaOH → NaCl + H 2 O

The molarity of the HCl is 0.8924 M.

Explanation:

Use dimensional analysis to solve the problem.

28.6 mL x () x () x () = 0.004147 moles HCl

Then we use M= moles/ liter  to find the molarity.

M = 0.004147 moles HCl / 0.005 L

M = 0.8294

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

um i think it might be a car?
