What volume of concentrated nitric acid (15.0 m) is
requiredfor the preparationof 2.00 l of 0.001m nitric acid
solution?

130 μL

Explanation:

The dilution formula is used to calculate the volume V₁ required:

C₁V₁ = C₂V₂

V₁ = (C₂V₂)/C₁ = (2.00L)(0.001M)/(15.0M) = 1.3 x 10⁻⁴ L or 130 μL

(1.3 x 10⁻⁴ L)(10⁶ μL/L) = 130 μL

increased stability in the completion of fluorine's outer shell.

that's what i got you can count the number of atoms
