Concentrated hcl has a specific gravity of 1.185 and is 36.5% w/w in hcl so 88 ml concentrated solution and in that add water
Here given data is concentrated hcl has a specific gravity of 1.185 and is 36.5% w/w in hcl and 88 ml concentrated solution 1.0 l of 0.050 m hcl would be prepared from the concentrated reagent because to make total 1 litre so we have to make total volume in that flask so to make total volume we have to take 88 ml of concentrated solution and add water to make a total of 1 litre to make 1.0 litre hcl add 88ml hcl concentrated solution and add water to make volume.
So, 1.0 l of 0.050 m hcl would be prepared from the concentrated reagent we have add water on it
