Fundamentals A A.2 The density and melting point are physical properties. The flammability of acetone is a chemical property. A.5. (a) physical; (b) chemical; (c) chemical A.10 (a) 5x10 5 pm = 5x10 -5 cm; (b) 5x10 -2 cm; (c) 2x10 - 4 dm = 2x10 - 3 cm Therefore, (b) is the largest A.14 105.50 g - 43.50 g = 62.00 g = mass of water d = m/V V = m/d = Mass of water / density of water = 62.00 g / 0.9999 g cm -3 Volume of water = 62.00 cm 3 = volume of container Density of liquid = mass of liquid/volume of container density of the liquid = [96.75g-43.50g]/ 62.00 cm 3 =0.8589 g cm -3 A.17 , rearrangegives m m d V V d = = 3 3 20.0 g V 7.41 cm 2.70 g .cm Since the area is 1 centimeter, the thickness must be 7.41 cm. = = A.21 (a) 4.82 nm × ( 1nm 1000pm ) = 4.82 × 10 3 pm (b) ( min 1.83mL )× ( 1mL 1cm 3 )× ( 3 3 1cm 1000mm )× ( s 60 min 1 ) = 30.5 mm 3 /s (c) 1.88 ng × ( ng 10 1g 9 )× ( g 10 1kg 3 ) = 1.88 × 10 −12 kg (d) ( 3 cm 2.66g )× ( 1000g 1kg )× ( 3 3 6 1m cm 10 ) = 2.66 × 10 3 kg/m 3
