Please help me. My chemistry teacher is not teaching us doing this epidemic

The answer to your question is below

Explanation:

1.-

Data

[HCl] = 0.3 N

Volume a = 6 ml

[NaOH] = ?

Volume b = 12 ml

Formula

                   [HCl] x Volume a = [NaOH] x Volume b

-Solve for [NaOH]

                   [NaOH] = [HCl] x Volume a / Volume b

-Substitution

                   [NaOH] = 0.3 x 6 / 12

-Simplification

                   [NaOH] = 0.15 N

2.-

Data

[H₂SO₄] = 7 N

Volume a = 12 ml

[KOH] = 3 N

Volume b = ?

Formula

                [H₂SO₄] x Volume a = [KOH] x Volume b

-Solve for Volume b

                Volume b = [H₂SO₄] x Volume a / [KOH]

-Substitution

               Volume b = 7 x 12 / 3

-Simplification

               Volume b = 28 ml

i just got this problem. it's 90.3

lol for the pointsss
