Achemist must prepare of aqueous potassium permanganate working solution. he'll do this by pouring out some aqueous potassium permanganate stock solution into a graduated cylinder and diluting it with distilled water. calculate the volume in of the potassium permanganate stock solution that the chemist should pour out. round your answer to significant digits.

V₁ = 228 mL

Explanation:

There is some info missing. I think this is the original question.

A chemist must prepare 575 mL of 50.0 mM aqueous potassium permanganate (KMnO₄) working solution. He'll do this by pouring out some 0.126M aqueous potassium permanganate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the potassium permanganate stock solution that the chemist should pour out. Round your answer to 3 significant digits.

We want to prepare 575 mL (V₂) of a 50.0 mM solution (C₂). To do so, we start, from a stock solution of concentration C₁ = 0.126 M. In order to find the volume V₁ that the chemist should pour out, we will use the dilution rule.

C₁ × V₁ = C₂ × V₂

0.126 M × V₁ = 50.0 mM × 575 mL

0.126 M × V₁ = 50.0 × 10⁻³ M × 575 mL

V₁ = 228 mL

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
