A student titrated 0.478 g of a weak acid with 0.217 M NaOH solution. How many moles of weak acid were in solution, if its molar mass was 168.45 g/mol

The moles of weak acid in the solution are moles

Explanation:

To calculate the number of moles, we use the equation:

We are given:

Given mass of weak acid = 0.478 g

Molar mass of weak acid = 168.45 g/mol

Putting values in above equation, we get:

Hence, the moles of weak acid in the solution are moles
