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

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.

(b) which contains higher levels of vitamin b, oranges or spinach?

you can eliminate a, c, and d because they are questions based on opinions.
