Quelle sera la molarité de la solution résultant de 20 ml d’ hno3 3,0m avec 80 ml d’eau?

The molar concentration will be 0,60 mol·L⁻¹.

You are diluting the nitric acid with water, so you can use the dilution formula

c₁V₁ = c₂V₂

We can solve this equation to get

c₂ = c₁ × V₁/V₂

c₁ = 3,0 mol·L⁻¹; V₁ = 20 mL

c₂ = ?;                V₂ = 20 mL + 80 mL = 100 mL

∴ c₂ = 3,0 mol·L⁻¹ × (20 mL/100 mL) = 0,60 mol·L⁻¹

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

ugh fiel iente of insistí is did kiwis jaj
