Measuring Matter  (Section 14-2)

1. Mass –
    A. Measurement of how much matter it contains
    B. Units of mass – gram, kilogram
2. Volume –
    A. Amount of space matter occupies
    B. fig. 8 (pg. 447)
    C. Rectangular objects
        1. V = L x W x H
        2. multiply units
    D. 1 mL = 1 cm3
3. Density –
    A. How much mass is contained in a given volume
    B. D=M/V
        1. D = density
        2. M = mass
        3. V = volume
    C. Units are g/cm³
