How do you find the molarity(M) of NaOH in this reaction:
2NaOH(aq) + H2C2O4-H2O > Na2C2O4(aq) + 2H2O
The only given information is 0.2079g of H2C2O4-2H2O
This problem can not be solved without the volume of NaOH used in the titration.
0.2079 g/molar mass H2C2O4.H2O = moles H2X2O4.H2O (note: you typed H2O one place and 2H2O another).
From the equation, moles NaOH = twice the moles of the oxalate.
Then MNaOH = moles NaOH/L NaOH.
Hydrochloric acid is sold as a concentrated acqueous solution.
If the molarity of HCl is 12.0 and its density is 1.18 g/ml. calculate
A) MOLALITY
B)THE % BY MASS OF HCl in the solution
See you post above and the response by Bob Pursley. It isn't a good idea to piggy-back your post onto that of another.
To find the molarity (M) of NaOH in the reaction, you need to follow these steps:
Step 1: Calculate the number of moles of H2C2O4-2H2O.
To calculate the number of moles, you divide the given mass (0.2079g) by the molar mass of H2C2O4-2H2O. The molar mass of H2C2O4-2H2O can be calculated by adding up the atomic masses of its constituent elements from the periodic table.
Step 2: Use the stoichiometry of the reaction to determine the number of moles of NaOH.
From the balanced chemical equation, you can see that there is a 1:2 mole ratio between NaOH and H2C2O4-2H2O. This means that for every 1 mole of H2C2O4-2H2O reacted, 2 moles of NaOH are consumed. So, you multiply the number of moles of H2C2O4-2H2O calculated in step 1 by 2 to obtain the number of moles of NaOH.
Step 3: Calculate the volume of the NaOH solution.
To calculate the volume, you need the number of moles of NaOH and its molarity. However, you don't have the molarity of NaOH given in this case. So, you would need additional information such as the volume of the NaOH solution used in the reaction or the concentration of NaOH solution if provided. Without this information, it is not possible to determine the molarity of NaOH in the given reaction.
Note: It is important to have all the necessary information to solve a given problem. In this case, the molarity of NaOH or the volume of NaOH solution used in the reaction is required to calculate the molarity of NaOH.
