How many moles are in 100mg of citric acid?

Answer 1

First you need the molar mass of citric acid. It is 192 g/mol. Now you can calculate the number of moles:

0.1 g x (1 mol/192 g) = 0.00052 mol

Answer 2

To calculate the number of moles in 100mg of citric acid (C6H8O7), first determine its molar mass by adding up the atomic masses of each element: C(12.01) + H(1.01) + O(16.00) x 7. Convert 100mg to grams (0.1g) and then divide the mass by the molar mass of citric acid to find the number of moles.
