Thanks for your marvellous help...

So if I use the density and volume to find the mass of the solute. I can then divide the solute mass by the total solution mass and multiply by 10^6 to find the concentration in ppm?

It doesn't matter. Thanks anyway.

Am I on the right track by the way? Is that the correct answer for mass and if so what do I do with the answer and how do I convert the answer to mg/l? Once I understand what I'm doing I should be ok in the future.

I meant 10ppm harmed particular species of fish and the same could apply in our aquariums.

Well it can have quite harmful respiratory effects on humans if inhaled in only small amounts but people readily use it as a carbon source for aquatic plants in aquariums. Metricide 14 is one particular brand which is 2.8% glut and the rest Distilled water. I have read studies that...

C=m/v Although this is quite condescending it fun. Mass = density x volume = 1.06 x 1000ml = 1060grams ?

Find the mass?

I sort of do with the help of Google. Not quite a maths or chemistry guru. I got an answer of 2.8ppm but I don't know if this is right. Was just trying to confirm and this seems to be the place to come. Borek has been very helpful in the past.

Molecular mass is 100.1 g/mol and density is 1.06 g/ml ThAnks

1 litre solution containing 28ml of glutaradehyde and the rest distilled water. What would be the concentration of glutaradehyde in solution in mg/l please.

Yes thank you. I wanted to split the phosphate away from the potassium to make the maths easier. I thought if I could get the phosphate part right I could work them as a whole if needed. It doesn't have to be overly precise it since fertilisers come dry it is useful to know exactly what you...

Thanks. It's actually mono potassium phosphate used as a plant fertiliser or on this case as a nutrient for autotrophic bacteria during nitrification. I was more interested in the math. I gather that what you are saying is it would not be pure phosphate and that the same would apply with the...

Way*

If I add 1 gram of phosphate to 20 litres of water. What would the concentration of phosphate in solution in ppm? I have somehow come up with 50ppm does this sound right? To achieve 1ppm phosphate in 20l of water I would require 0.02g? Or am a weigh off?
