41. To neutralize 1 mol of sulfuric acid, 2 mol of

sodium hydroxide are required. How many liters
of 1 M NaOH are needed to exactly neutralize
1 1 of 1 MH,SO,?
wa (22 605 (1) A.

Answer 1

• 2 liters

Step-by-step explanation:

Some data are garbled, but they seem to be 1 liter of 1M H₂SO₄. Based on that, the solution is as follows:

1. Data:

a) mole ratio: 1 mol H₂SO₄ : 2 mol NaOH

b) NaOH:

i) V = ?

ii) M = 1 M

c) H₂SO₄ :

i) V = 1 liter

ii) M = 1 M

2) Solution

a) Determine the number of moles of H₂SO₄

Use the molarity (M) formula:

• M = n/V ⇒ n = M × V = 1M × 1 liter = 1 mol H₂SO₄

b) Determine the number of moles of NaOH

Set a proportion with the mole ratio:

`(1molH_2SO_4)/(2molNaOH)=(1molH_2SO_4)/(x)\\\\\\x=2molNaOH`

c) Determine the volume of NaOH

Use the molarity formula:

• M = n/V ⇒ V = n/M = 2mol / 1M = 2 liter ← answer
