Document Summary

Volume = l or ml (1 ml = 1 cm3) Density= kg/m3 but usually g/ml = g/cm3. Concept area 2: exponents and scientific notation: scientific notation= ___ x 10 . Answer rounds to the number in the problem with the least amount of significant figures. Answer rounds to the amount of decimal places of the number with the least amount of places after the decimal points. Concept area 4: basic definitions: atoms the smallest unit of an element that retains the chemical nature of the element. High precision + high accuracy = small random error. All points fall near each other and next to the actual value. High precision + low accuracy = systematic error. All points fall near each other but far from actual value. Low precision + average close to actual = large random error. All points are scattered but average is close to actual value. All points are scattered and average is not close to actual value.
