Chapter 1, Problem 1.30E

The “Chemistry in Focus” segmentTiny Thermometersstates that the temperature range for the carbon nanotube gallium thermometers is 50 °C to 500 °C. a. What properties of gallium make it useful in a thermometer? b. Determine the useful temperature range for the gallium thermometer in Fahrenheit units.

What is density? Give two examples of possible units for density.

A children's pain relief elixir contains 80. mg acetaminophen per 0.50 teaspoon. The dosage recommended for a child who weighs between 24 and 35 lb is 1.5 teaspoons. What is the range of acetaminophen dosages, expressed in mg acetaminophen/kg body weight, for children who weigh between 24 and 35 lb?

Mass of group is in-lbs is 475.0lbs convert it to  kg  cg

A student pours 40.0 g of water at 17 degrees celsius into a beaker containing 111.2 g of water at 17 degrees celsius. The density of water is at 17 degrees celsius is 1.00 g/mL.  (a) What is the final mass?  (b) what is the final temperature?  (c) What is the final density?

(d) Bamboo can grow up to 60.0 cm/day. Convertthis growth rate into inches per hour.

The density of pure copper is 8.89 gram/centimiter cube (at 20 degree celcius). a. Calculate the mass in kg of a copper cube with dimensions 1 feet 4 inches on all three sides. b. Calculate the volume in inch cube of of a 5.0 kg bar of copper.

Suppose a child’s normal temperature is 98.6°F and the only thermometer available,which is Celsius, indicates that the child’s temperature is 37°C. Does this reading indicate that the child’s temperature is normal?

III > f. Is the density of the solution an intensive property or an extensive property? 8. Create a concept map that illustrates the relationship between scientific notation and unit prefixes. 9. A balloon is filled with helium at a temperature of 25.0°C. a. Calculate the temperature of the helium in degrees Fahrenheit. b. Calculate the temperature of the helium on the Kelvin scale. c. Gas density decreases with increasing temperature. What would you observe if you heated the balloon? d. Gas density increases with decreasing temperature. What would you observe if you cooled the balloon? e. Is helium a pure substance or a mixture? f. Is helium an element or a compound? 10. The diameter of an aluminum atom is 250 picometers (pm) (1 pm = 10-¹2 m). How many aluminum atoms must be placed end to end to make a "chain" of aluminum atoms 1 ft long?
