1% solution = 1 gram per 100 mL, 10 grams per liter 20 grams
148g
Assuming that the density of the solution in 1 gdm-3 : 1 litre = 1dm3= 1 kg = 1000g
ungimat
1 liter = 1000 mL 1 gram = 1000 mg So there are 45,000 mg in 1 liter divided by 1000 mg per gram = 45 grams/liter
Depends on the material in question.

HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.
20% salt solution is the equivalent of adding 200gr salt in a 800 ml (1000ml -200ml) of water. you now have one liter of a 20% solution.
129 (grams per liter) = 129,000,000 micrograms per liter.
The mass of NaCl is 14,61 g.
