A. At STP, what is the volume of 708 mol of nitrogen gas? 708 mol = 708 mol X L B. A sample of hydrogen gas occupies 14.1 L at S
elena-14-01-66 [18.8K]

Answer:

A. 15859.2 L or 15900 L

B. 0.629 mol

Explanation:

At STP, one mole is equal to approximately 22.4 L

L or mL is volume, so you are attempting to solve for L or mL.

A.

708 mol x (22.4 L/1 mol) = 15859.2 L (w/ significant figures included - 15900 L)

B.

(14.1 L) x (1 mole/ 22.4 L) = 0.629 mol.

In a titration, 25.0 mL of a 0.40 M NaOH solution is used to neutralize 10.0 mL of HCl. Calculate the molarity of the acid.
laiz [17]

The molarity of the HCl acid will be 0.001 M.

<h3>What is Neutralization ?</h3>

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H⁺ ions and OH⁻ ions to generate water.

This is the neutralization of a strong acid (HCl) and a strong base (NaOH), which is ruled by this equation :

HCl (aq) + NaOH (aq) → NaCl (aq) + H₂O (l)

Mole Ratio : 1 mol HCl : 1 mol NaOH

Formula used ;

Molarity  = number of moles  / Volume  (in liters)

Solve for n ;

n = M × V

Substitute values and compute ;

n = 0.40 M × 0.025 liter = 0.01 moles NaOH.

As the molar ratio is NaOH : HCl

Therefore, there will be same number mole for the HCl

Now, Molarity of HCl Solution ;

Molarity = n / volume

Molarity = 0.01 / 10

             =  0.001 M HCl

Hence, The molarity of the HCl acid will be 0.001 M.
