Want this question answered?
ethanol
This depends on the nature of this solid, temperature, pressure, stirring, particles dimension etc.
i performed this experiment and it comes out around 60 (radians*100cm3/gm*dm) where length of polarimeter tube was 2 dm and concentration was varied from 40 gm/100cm3 to 20gm/100cm3
it is equal to 100g
Not all the solids will dissolve in water. Different solids have different solubilities (some will dissolve more than others). The higher temperature, the more will dissolve
ethanol
No, 100cm3 is only 0.026 gallon.
When 100cm3 of 1.0 molar of sodium hydoxide solution at 200oc was added to 100cm3of1.0 molar of HCL solution at 200oc,then the temperature of HCL rose to 26.8oc.calculate the standard heat of neutralisation?(Given that the specific heat capacity of water is 4.2KJg-1k-1)

1 gallon has more volume. 100cm3 is basically 1/10th of a liter which is 1,000cm3
What is the volume of 35.7g of sodium chloride in 100cm3 of cold water?
No.
you divide by 1000 to convert from cm3 to dm3, so 100cm3 is 0.1dm3

right i dont know this 4 sure but because u want a 0.1 mol/dm3 and u only need 100cm3 u will need 0.01mols of copper sulfate to dilute in 100cm3. soo now u have a solution that is 0.01mols per 100cm3 or 0.1 mols per 1000cm3 (dm3)
it is equal to 100g
Solubility of Sodium Chloride: 35 g/100cm3 or 35 g/100 mL Solubility of Sodium Nitrate: 87 g/100cm3 or 87 g/100 mL In case you didn't know, one mL is equivalent to one cm3. the "3" is subscript for "cubed" in case it was confusing. These substances have these solubilities at room temprature.
