###### Question details

Please work out both step by step.

Example 2. Find the molar concentration of a 2% solution if the molecular weight of the solute is 200. I know we get to 2g/0.1 L but I am not understanding where these number are coming from. I believe the 2% of 200 is the 2g but where is the 0.1 L coming from (I thought it was over 1L) Also please work the entire problem out. Id really appreciate it.

Example 3. Find molar concentration of pure water. 1 L of water has the mass 1000 g and the molecular weight of water is 18.
