Chapters 1 and 2 - math and concept review concept area 1 - metric system: using the information about metric prefixes, symbols and multiples, you should be able to convert between units. Know these prefixes: you should be able to identify the common metric units for length, mass, temperature, volume and density. Si units: length = m, mass = kg, temp = kelvin (k, volume = l or ml (1 ml = 1 cm3, density= kg/m3 but usually g/ml = g/cm3. Concept area 3 - significant figures: be able to report measurements to the correct number of decimal places. The following abilities need to be demonstrated in handling significant figures. Determining which digits are significant: non-zero digits are always significant, leading zeros are not significant, confined zeros are always significant, trailing zeros are zeros at the end of a number.
