.44.00-le sample from a person su diabetes mellitus has a mass of 4.004 g. 2.7 d. A solid object has a mass of 1.65 lb and a volusce 170 mL What is the density (g/mL) of each of the following samples? a. A lightweight head on a golf club is made of titanium. 2.69 The volume of a sample of titanium is 114 cm3 and the mass is 514.1 g. 2.74 2.75 Lightweight heads on golf clubs are made of titanium. b. A syrup is added to an empty container with a mass of 115.25 g. When 0.100 pt of syrup is added, the total mass of the container and syrup is 182.48 g. 2.76 Clinica 2.77 S a. 115.25 g 182.48 g b. c. A block of aluminum metal has a volume of 3.15 L and a mass of 8.51 kg.Explanation / Answer
Q2.69)
a)
Mass of golf club head = 514.1 grams
Volume of golf club head = 114 cm^3
Density of the sample = Mass of sample/Volume of sample = 514.1 grams/114 cm^3 = 4.509 g/cm^3 = 4.51 g/cm^3 (in three significant digits)
a)
Mass of empty container = 115.25 grams
Total mass of container = Mass of empty container + Mass of syrup
182.48 = 115.25 + Mass of syrup
Mass of syrup = 67.23 grams
1 pint = 473.176
0.1 pint = 47.3176 mL = 47.3176 cm^3
Density of the sample = Mass of sample/Volume of sample = 67.23 grams/47.3176 cm^3 = 1.421 g/cm^3
c)
1 L = 1000 mL
Volume = 3.15 L = 3.15L * 1000 mL/1L = 3150 mL
1 Kg = 1000 g
Mass = 8.51 Kg = 8.51 Kg * 1000g/1Kg = 8510 g
Density of the sample = Mass of sample/Volume of sample = 8510 grams/3150 cm^3 = 2.701 g/cm^3
