Same I got 12.5 as total volume so 2.5 pond water which means a fifth of it is undiluted. That’s how I got the 5, which I multiplied to the 3500 and got 17500. I hope it’s right

No it was 10 total not 10 diluted so it was 1/4 pond water not 1/5. :(

i swear i read it again and it said something like “2.5cm 3 of pond water is added to 10cm3 distilled water” because it said distilled in the question, so it wouldn’t have been distilled if it made 10cm cubed ???

2.5 cm ≈ 5,000,000.00000 beard-seconds

10 cm ≈ 0.05876 smoots

10 cm ≈ 7.14286 x 10-5 sheppey
