    We have 0.0170 moles of butyric acid

    Explanation:

    Step 1: Data given

    Density of butyric acid = 0.959 g/mL

    Temperature = 20.0°C

    Volume = 1.56 mL = 0.00156 L

    Step 2: Calculate mass

    Density = mass / volume

    mass = density * volume

    Mass = 0.959 g/mL * 1.56 mL

    Mass = 1.496 grams

    Step 3: Calculate Number of moles

    Number of moles = mass / molar mass

    Number of moles = 1.496 grams / 88.11 g/mol

    Number of moles = 0.0170 moles

    We have 0.0170 moles of butyric acid
