Chapter 1, Problem 3P

A) What is an equation to equate KE and GPE?  B) A gas is held in a container of 15 m^3 in volume and a pressure of 5 Pa. If the volume isincreased to 26 m^3 what is the pressure of the gas? c)A syringe has a volume of 5 cm^3 and a temperature of 300 k. Upon heating the syringeexpands to a volume is now 5.5cm^3, what is the temperature of the syringe?

A sample of pure iron has a mass of 13.8 g. Calculate the number of moles in the sample and iron atoms in the sample.   (a) moles in the sample moles (b) iron atoms in the sample atoms

Manufacturers of headache remedies routinely claim that their own brands are more potent pain relievers than the competing brands. Their way of making the comparison is to compare the number of molecules in the standard dosage. Tylenol uses 325 mg of acetaminophen (C8H9NO2) as the standard dose, while Advil uses 2.00 x 102 mg of ibuprofen (C13H1802). Find the number of molecules of pain reliever in the standard doses of (a) Tylenol and (b) Advil. (a) Number Units (b) Number Units

The unit cell of platinum has a length of 392.0 pm along each side. Use this length (and the fact that Pt has a face-centered unit cell) to calculate the density of platinum metal in kg/m3 (Hint: you will need the atomic mass of platinum and Avogadro's number).

Calculate the formula weight of (a) Al1OH23, (b) CH3OH,and (c) TaON.

In an experiment to measure the specific heat capacity of Aluminum three values, 0.25 Cal/gm.Co, 0.20 Cal/gm.Co, 0.19 Cal/gm.Co, are determined, the percent error of their mean is: (Given that the accepted value of is 0.22 Cal/gm.Co) a. 4.5% b. 3.0 % c. 5.5% d. 7.2%

The following equation of Van Der Walls Find value of volume v where: p=1 atm, T= 300°K, R=0.082054 atm/mole.°K, a= 3,b=0.04267, take start point v, = 24 correct to 4D places. use bisection method (p+)v-b) = RT a

Q1 : limx→1 x(1 – cos-)

The density of iron is 8 grams per cubic centimeter. The atomic mass of iron is 56 grams per mole and there are Avogadro’s number of atoms in a mole. Calculate the diameter of an iron atom to two significant figures.
