26.5 moles of a .2 M aqueous solution of NaOH is required to titrate 50 ml of an aqueous solution of HNO3, what is the concentration of HNO3. I don't want the answer, I want to know how to do it.
To determine the concentration of HNO3, you can use the concept of stoichiometry and the equation for the reaction between NaOH and HNO3. The balanced equation is:
HNO3 + NaOH -> NaNO3 + H2O
First, convert 50 mL of the HNO3 solution to moles. You can do this by multiplying the volume (50 mL) by the molarity of the NaOH solution (0.2 moles/L). This will give you moles of NaOH used in the titration.
Next, since the balanced equation tells us that 1 mole of NaOH reacts with 1 mole of HNO3, the moles of NaOH used in the titration will be equal to the moles of HNO3 present in the 50 mL solution.
Now, divide the moles of HNO3 by the volume of HNO3 used in the titration (which is 50 mL) to find the concentration in moles per liter (M).
Finally, you can express the concentration in the desired units, such as moles per liter (M).
By following these steps, you will be able to determine the concentration of HNO3 in the given solution.
