- <em>Assuming copper sulfate has same density as water</em>
<u>Chemical to water ratio as per given is:</u>
- 250 kg : 1000 liter = 1 kg : 4 liter
Lab solution is 350 ml
<u>Converting to same ratio as above:</u>
350/(1 + 4) = 70 ml
- 70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 ml
Answer is 0.07 kg
Repeated fractions are written with 9's in the denominator.
