How many milliliters of 0.0050 N KOH are required to neutralize 53 mL of 0.0050 N H2SO4 ?
Tatiana [17]

Answer is: 53 milliliters of KOH are required.

Balanced chemical reaction:

2KOH(aq) + H₂SO₄(aq) → 2H₂O(l) + K₂SO₄(aq).

N(KOH) = 0.0050 N; normality of potassium hydroxide solution.

V(H₂SO₄) = 53 mL; volume of sulfuric acid.

N(H₂SO₄) = 0.0050 N; normality of sulfuric acid.

Na·Va  = Nb·Vb.

0.0050 N · 53 mL = 0.0050 N · V(KOH).

V(KOH) = 53 mL; volume of potassium hydroxide solution.

Which of the following steps correctly converts 6 grams of fluorine to an equivalent number of moles of fluorine?
kati45 [8]

Answer:

Divide 6 grams by the atomic mass of fluorine.

Explanation:

Number of moles = Mass / atomic mass of fluorine

Given data:

Mass of fluorine = 6 g

How to convert into moles of fluorine = ?

Solution:

Number of moles = Mass / atomic mass of fluorine

Number of moles = 6 g/  19 g/mol

Number of moles =  0.32 mol

So in order to convert the 6 g of fluorine into moles we have to divide the 6 by atomic mass of fluorine.

what is the molarity of 20.0 ml of a KCl solution that reacts completely with 30.0 ml of a 0.400 M Pb(NO3)2 solution?
Alex17521 [72]

Answer:

[KCl] = 1.2 M

Explanation:

We need to complete the reaction:

2KCl(aq) + Pb(NO₃)₂(aq)  → 2KNO₃(aq) + PbCl₂(s)↓

By stoichiomety we know that 1 mol of chloride needs 1 mol of nitrate to react:

Let's find out the moles of nitrate, we have:

Molarity = mol/volume(L)

We convert the volume → 30 mL . 1L/1000mL = 0.030L

Molarity . volume(L) = moles → 0.400 M . 0.030L = 0.012 moles

Therefore, we can make a rule of three.

1 mol of nitrate reacts with 2 moles of chloride

Then, 0.012 moles of nitrate must react with (0.012 . 2) / 1 = 0.024 moles of KCl

We convert the volume from mL to L → 20 mL . 1L /1000mL = 0.020L

Molarity = mol /volume(L) → 0.024 mol /0.020L = 1.2 M
