Subject: mls and grams If I have a 2000litre pool and need to put 2mg of chlorine per litre, how many mls do I need to add? |
JJ,
Since the pool holds 2000 litres of water and you are to add 2 mg of chlorine per litre you need to add 2000 
2 = 4000 mg of chlorine which is 4 grams of chlorine. Grams are units of mass and millileters are units of volume and I can't convert one to the other without knowing the density of the material.
