Question
Identify each of the following as measurements of length, area, volume, mass, density, time, or temperature: (a) ns; (b) 10.0 kg/m^3; (c) 1.2 pm; (d) 750 km^2; (e) 83k; (f) 4.0 mm^3. Carry out the following operations, and express the answer with the appropriate number of significant figures and units. (a) (5.231 mm)(6.1 mm); (b) 72.3 g/1.5 mL; (c) 12.21 g + 0.0132 g; (d) 31.03 g + 12 mg. Drug medications are often prescribed on the basis of body weight. The adult damage of eilcophyllin, a drug used to treat asthma, is 6 mg/kg of body mass. Calculate the done milligrams for a 150-lb person. A man who is 5 ft 8 in. tall weighs 160 lb. What is his height in centimeters and his mass in kilograms? Determine the boiling point of water at 620 mm Hg. A pipet delivers 10.0, 10.2, 10.8, and 10.6 mL in consecutive trials. Find the mean volume and the average deviation from the mean. A 141-mg sample was placed on a watch glass that weighed 9.203 g. What is the weight of the watch glass and sample in grams?Explanation / Answer
QUESTION 4
Man height is = 5 foot, 8 inch
Man weight is = 160 lb
1 foot = 30.48 cm
hence 5 foot = 152.4 cm
1 inch = 2.54 cm
Hence 8 inch = 20.32 cm
Hence total height = 152.4 + 20.32 = 172.72 cm
1 lb = 0.45359 Kg
Hence 160 lb = 160 x 0.45359 = 72.5748 Kg
Man weight = 72.5748 Kg
Question 8
Weight of the sample = 141 mg = 0.141 gm
Weight of the watch Glass + sample = 9.203 gm
Weight of the watch Glass = 9.203 - 0.141 = 9.062 gm
