hello!!!

what volume of hydrochloric acid concentration 0.1 mol is required to neutralise 100 cm3 of sodium hydroxide solution concentration 0.1 mol

can you please expalin this question step by step i really don't understandand how to do it thank you very much

Step 1. Write and balance the equation.

HCl + NaOH ==> NaCl + H2O

Step 2.
How many mols NaOH do you have to neutralize?
M x L = mols = 0.1 M x 0.100 L = 0.01 mol NaOH.

Step 3.
Convert mols NaOH to mols HCl using the coefficients in the balanced quation.
0.01 mol NaOH x (1 mol HCl/1 mol NaOH) = 0.01 mol HCl needed.

Step 4.
M HCl = mols HCl/L HCl.
You have M HCl, you have mols HCl, calculate L HCl. I think the answer is 0.1 L or 100 cc of O.1 M HCl but check me out on that.

Of course! Let's break down the steps to solve this problem:

Step 1: Understand the question
The question is asking for the volume of hydrochloric acid needed to neutralize a certain volume of sodium hydroxide solution.

Step 2: Identify the given information
The question provides two pieces of information:
1. Concentration of hydrochloric acid: 0.1 mol
2. Volume of sodium hydroxide solution: 100 cm3

Step 3: Determine the balanced chemical equation
The balanced chemical equation for the neutralization reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) is:
HCl + NaOH -> NaCl + H2O

Step 4: Use the balanced chemical equation to find the stoichiometric ratio
From the equation, we can see that 1 mole of HCl reacts with 1 mole of NaOH. This means that the stoichiometric ratio is 1:1.

Step 5: Use the given volume and concentration to find the number of moles of NaOH
The number of moles is calculated using the formula:
moles = concentration × volume

In this case, the concentration is given as 0.1 mol, and the volume is given as 100 cm3. Therefore:
moles of NaOH = 0.1 mol/dm3 * (100 cm3 / 1000 cm3/dm3) = 0.01 mol

Step 6: Use the stoichiometric ratio to find the number of moles of HCl
Since the stoichiometric ratio is 1:1, the number of moles of HCl is also 0.01 mol.

Step 7: Use the concentration and number of moles to find the volume of HCl
The volume can be calculated using the formula:
volume = moles / concentration

In this case, the concentration is given as 0.1 mol, and the number of moles is 0.01 mol. Therefore:
volume of HCl = 0.01 mol / (0.1 mol/dm3) = 0.1 dm3

Step 8: Convert the volume to the desired unit
The desired unit is cm3, so we need to convert the volume from dm3 to cm3. Since 1 dm3 is equal to 1000 cm3:
volume of HCl = 0.1 dm3 * 1000 cm3/dm3 = 100 cm3

Therefore, 100 cm3 of hydrochloric acid with a concentration of 0.1 mol is required to neutralize 100 cm3 of sodium hydroxide solution with a concentration of 0.1 mol.
