A student needs to determine density of a liquid. The student determines mass of an empty.flask to be 251.21 g and then adds 224 mL of liquid to it. The mass of the flask with liquid is 451.13 g. What is the density of the solution in units of g/mL?

Calculating Volume Suppose you want to know the volume of a rectangular object, like one of the suitcases shown in Figure 3. First, measure the length, width, and height (or thickness) of the suitcase. Then multiply the measurements together. Volume = Length x Width X Height When you multiply the three measurements, you must also multiply the units. Units = cm X cm × cm = cm³ -63.5 cm 23 сm 43 cm FIGURE 3 Calculating Volume SEP Calculate Find the volume of the suitcase.

A certain city covers an area of 66.4 mi2. How many square kilometers is this? Use the conversion factor 1 mile = 1.61 km. Report your answer to the appropriate number of significant figures.

A piece of cardboard is 12.0 cm long, 6.3 cm wide and 0.75 millimeters thick. What is the volume of this piece of cardboard in cubic meters? Enter your answer in the space provided WITHOUT units. Make sure to round your answer to the correct number of significant figures. Please give the number as a normal number, do not use scientific notation.  (In example: a normal number = 4300 instead of the number being in scientific notation as = 4.3 X 103)

The average adult heart pumps about 84./mLs of blood at 72 beats per minute. Suppose you need to calculate how long it would take the average heart to circulate 3600.mL of blood. Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.
