What tool do I need to use to find the molar mass?

How are energy and mass connected during the formation of an atom?

For practice, the molecular formula for ascorbic acid is C6H8O6, and you used 6 g in this experiment, calculate the molarity of the ascorbic acid. Now calculate the concentration in moles per drop (assume 1 mL = 20 drops)
