What is the amount of potassium permanganate in 300mL of a 1 in 25 solution?

B8 grams

C12 grams

D14 grams

Show Suggested Answer

Suggested Answer: C

We have 1g of potassium permanganate in 25mL We have 300mL of solution

For every 25mL of that 300mL, we have 1g of KmnO4

300mL must have 12g of potassium permanganate (300ml/25mL)

I calculated it, and it's actually 12 grams. The formula is (Volume of solution in mL * % concentration) / 1000.

Hmm, this reminds me of that time I tried to make homemade lava lamps. Let's just say, the results were a little... explosive.

Well, if it's a 1 in 25 solution, then the concentration of the solute is 1/25, which is 0.04. Multiplying that by the volume of 300mL, we get 12 grams. I'll go with C.

Yeah, C seems to be the correct answer based on the concentration calculation.

Okay, let's think this through. 1 in 25 means 1 part solute to 25 parts solvent. So we need to find the amount of solute in 300mL of that solution.

Hmm, I'm pretty sure it's not 14 grams. That seems way too high for a 1 in 25 solution.
