I don't understand this question....
3. What will be the mass( in lbs) of a substance that has a density of 11.2 g/cm' and a volume of
a 4.37 cm ? (453.6 g = 1 lb)
4. Calculate the volume in L of 10.38 g of diethyl ether, an anesthetic that has a density of
0.713 g/mL?
5. A student performs an experiment to determine the density of an irregular shaped solid. The
mass of this solid was found to be 52.655 g. To find the volume of this irregular shaped solid,
student uses " displacement method" and records following data:
Initial water level in the graduated cylinder : 75.4 mL
Final water level in the graduated cylinder : 90.8 mL
Calculate,
Volume of the "irregular shaped solid" =
Density of the "irregular shaped solid" =
A patient was prescribed 125 mg of potassium, which is only available as a 0.28 g/mL
solution. How many mL of solution are required?
