100ppm means, you need 100mg in 1oooml. Thus, for 100ml solution, you will need 10mg of methanol to make 100ppm solution.
With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.
13.6% methanol solution.
Methanol absorbs a minor quantity of oxygen gas and forms a homogeneous solution.
Water and methanol are completely miscible (they will dissolve into each other in any proportion). A mixture of water and methanol will always form a clear solution (after sufficient mixing) unless there are impurities in either to start off with.
Put 0.9g of Nacl in a beaker and add distilled water to make up to 100ml. that is 0.9% Nacl (Normal saline Solution) From Tade Olubunmi Ademola

2.5gm require 100ml of solution 100ml solution require 2.5gm 50ml require 50x2.5/100=1.25ml
2.5 g of Nacl is to be dissolve in 100ml of water gives 10ppm of Na solution.
It is same, instead of water take methanol...

58 grams of NaCl in cylinder measure water to 100ml
Very simply 1g of ammonium thiocyanate and 100g (100ml) of water!
Very simply 2g of ferric chloride and 100g (100ml) of water!
