Question
Identify each of the following as measurements of length, area, volume, mass, density, time, or temperature: ns 10.0kg/m^3 1.2 pm. 750 km^2. and 83 K: 4.0 mm^3. Carry out the following operations and express the answer with the appropriate number of significant figures and units, (5.231 mmM6.1 mm), 72.3 g/1.5 mL. 12.21 g + 0.0132 g. and (d) 31.03 g + 12mg. Drug medications are often prescribed on the basis of body weight. The adult dosage of Elixophyllin, a drug used to treat asthma, is 6 mg kg of body mass. Calculate the dose in 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 9.98 g of water at 20 Degree C. What volume does the pipet deliver? A pipet delivers 10.4 mL 10.2 mL. 10.8 mL. and 10.6 mL in consecutive trials. Find the mean volume 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 glass and sample in grams?Explanation / Answer
Answer 1)
a) ns means nanoseconds and 1 ns = 10-9 s. TIME.
b) 10.0 Kg/m3. Kg for mass and m3 for volume. and ratio of mass to volume gives density.
DENSITY.
c) 1.2 pm means picometer and 10-12 m = 1 pm. LENGTH.
d) 750 Km2 i.e. Km2 = Km x Km = i.e. Length x Length gives AREA.
e) 83 K i.e. Kelvin a unit of TEMPERATURE.
f) 4.0 mm3 i.e mm x mm x mm i.e. length x length x length gives VOLUME.
