For this PreLab assignment we will assume all of the acid is the monoprotic acid acetylsalicylic acid (C9H8O4). [Note: for your analysis in the PostLab you will subtract the moles of salicylic acid from the total acid content to determine the amount of acetylsalicylic acid].

Answer:

0.0011 moles

Explanation:

Recall that;

Number of moles = mass of substance/ molar mass of the substance

Mass of asprin = 0.2001 g

Molar mass of asprin = 180.158 g/mol

Number of moles =  0.2001 g/180.158 g/mol

Number of moles = 0.0011 moles
