    9.09cm3

    Explanation:

    The following data were obtained from the question:

    Mass of dimethyl sulfoxide = 10g

    Density of dimethyl sulfoxide = 1.10gcm-3

    Volume of dimethyl sulfoxide = ?

    The density of a substance is simply the mass substance per unit volume of the substance. It is represented mathematically as:

    Density = Mass/volume.

    With the above formula, we can obtain the volume of dimethyl sulfoxide as follow:

    Density = Mass/volume

    1.10gcm-3 = 10g / volume

    Cross multiply to express in linear form

    1.10gcm-3 x Volume = 10g

    Divide both side by 1.10gcm-3

    Volume = 10g / 1.10gcm-3

    Volume = 9.09cm3

    Therefore, the volume of dimethyl sulfoxide the student should pour out is 9.09cm3
