Avagadro's number (6.023 × 1023) is a pure (unitless) number which serves as a good standard for measuring the number of molecules in ideal gases at STP. A)What is the volume, in cubic kilometers, of Avogadro’s number of sand grains, if each grain is a cube with an edge length of 1.3 mm and the cubes are densely packed (with no air between them). B) How long, in kilometers, would a beach have to be for this sand to cover it to a depth of 10.0 m? Assume a beach is 100.0 m wide, and you can neglect the air spaces between the grains.

mol K 1) The Ideal Gas Law, PV = RT, relates the pressure (P, in pascals), temperature (T, in Kelvin), and volume (V, in cubic meters) of 1 mole of a gas (with R = 8.314 as the universal gas constant), and describes the behavior of gases that do not liquefy easily, such as oxygen and hydrogen. We can solve the ideal gas law for volume and hence treat the volume as a function of the pressure and temperature: V(P,T) = 8.314T P 1000 tells us about a key relationship between a) Explain in detail what the trace of V with P two quantities. b) Explain in detail what the trace of V with T = 5 tells us. c) Explain in detail what the level curve V = 0.5 tells us. d) Use 2 or 3 additional traces in each direction to make a rough sketch of the surface over the domain of V where P and T are non-negative.
