    71.4 cm³

    Step-by-step explanation:

    Density = mass/volume

    D = m/V Multiply each side by V

    DV = m Divide each side by D

    V = m/D

    dа ta:

    m = 90.0 g

    D = 1.26 g/cm³

    Calculation:

    V = 90.0 g * (1 cm³/1.26 g)

    = 71.4 cm³

    The student should measure out 71.4 cm³ of glycerol.
