Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. One potential application of nanotechnology is the construction of artificial cells. The simplest cells would probably mimic red blood cells, the body's oxygen transporters. For example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. If the person needed additional oxygen-due to a heart attack perhaps, or ror the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. Suppose that the nanocontainers were cubic and had an edge length of 25 nanometers. (a) What's the volume of one nanocontainer? (Ignore the thickness of the nanocontainer's wall) (In liters) (b) Suppose that each nanocontainers could contain pure oxygen pressurized to a density of 85 g/L. How many grams of oxygen could be contained by each…

You are a pharmacist at a drug store and a woman approaches you frantically, holding a bottle of Children's Advil. Her daughter has a fever and the company changed it's formulation. Now, she doesn't know how much medicine to give her daughter. With the old formulation, she gave 1.875 mL dosage that contained 50 mg of ibuprofen per 1.25 mL. The new formula contains 100 mg of ibuprofen per 5 mL. How many mL of medicine should the woman give her daughter?
For liquid B, you decide to use a 50 mL burette to once again dispense 5.00 mL of liquid B into a convenient container. You find that the empty container has a mass as 3.05 grams. After obtaining the mass of the empty container you place it beneath the burette and open the stopcock valve. Although you try to stop the flow of liquid B at exactly the 5.00 mL mark you overshoot slightly and end up dispensing 5.14 mL. What is the mass of liquid-B that was dispensed if you continue with the density determination for liquid B and find that the mass of the container plus the 5.14-mL of liquid B is 7.63-grams?
