Scientist 1 analyzed the compounds first then gave it to scientist 2 for the next test. Scientist 2 needs to know the molar mass of the active compound. The concentration of the solution they created is twenty percentw/w from the solid active compound and it has a density of 1.40 grams per millilitre. Ten microliters were taken from this solution and mixed with one hundred ninety microliters of reagent and water. After analyzation, it showed that the compound's concentration is Five times ten raised to negative four M i. Find the concentration of the twenty percentw/w solution. The concentration must be in the form of molarity ii. Explain the reason why the concentration of the solution was expressed as %w/w initially? iii. Determine the active compound's molar mass.
