4. The molar mass of starch is 359.33 g/mol. Given that the concentration of starch in the reaction mixture is 0.006% m/v, a. Calculate the molarity of starch in the reaction mixture. b. If 3 drops of a starch solution were added to the reaction mixture to obtain a concentration of 0.006% m/v, and each drop is 0.05 mL, calculate the molarity of the starch solution.

Answer :

359.33 g/mol is indeed the molar mass for starch. In light of the reaction mixture's 0.006% m/v starch concentration.

What exactly are molar mass and mol?

The SI unit used to measure a material's amount is the mole. The word "mol" is used to denote it. It is also referred to as the area of a substance containing an equal number of distinct entities. A substance's molar mass is the weight in kilograms with one mole of that substance.

What exactly are molarity and normality?

As a double of molarity, normality can be defined. While "molarity" refers to the amount of a substance or ion in a liquid, "normality" relates to the molarity of just the base or acid component, respectively.
