I’ve been stuck on this for way too long. (:

Answer :

Part 1 : conversion factor required for 30%(m/m) NaCl solution.

30%(m/m) NaCl solution that means 30 grams of NaCl is present in 100 gram of solution.

Conversion factor :

Part 2 : conversion factor required for 8%(v/v) ethanol solution.

8%(v/v) ethanol solution that means 8 ml of ethanol is present in 100 ml of solution.

Conversion factor :

Part 3 : conversion factor required for 14%(m/v) fructose solution.

14%(m/v) fructose solution that means 14 grams of fructose is present in 100 ml of solution.

Conversion factor :

Part 4 : conversion factor required for 5.0 M HBr solution.

'M' represent the 'molarity' which is defined as the number of moles of solute present in one liter of solution.

5.0 M HBr solution that means 5 moles of HBr is present in 1 liter of solution.

Conversion factor :
