Please help, I only need help with part b. Thanks! 2. A standard solution is prepared by dissolving 5.30g Sodium carbonate in 250cm^3 of water in a volumetric flask

2a) concentration of solution is 21.2 g/dm3

2b) a 10cm3 sample of this solution is removed by a bulb piper and diluted with water to the final volume of .100dm3. Calculate the concentration in mol/dm3 of the diluted solution.

Pure water and aqueous solutions of table salt, acid, base, and table sugar are used ... Light bulb connected to electrodes power cord and electrodes, beaker, water, ... it dissociates almost completely, creating a concentration of sodium ions and ... a mixture of water molecules, at a concentration of roughly 55 moles per liter.

Explanation:
