    Did I Calculate the Molecular Volume Fraction Correctly?

    (2.5x10^-10)/2 = 1.25x10^-10 m V= (4 x pie x (1.25x10^-10^3)/3 = 8.18123x10^30 m^3 N= (PV)/(RT) = .000193 Molecules (3.19 x 10^-2 m^3)/(.000193 Molecules) =165.155 m^3 Did I do part (b) right?

    Did I Calculate the Molecular Volume Fraction Correctly?

    A gas has a temperature of 310 K and a pressure of 101 KPa. (a) Find the volume occupied by 1.25 mol of the gas, assuming it is ideal. (b) Assuming the gas molecules can be approximated as small spheres of diameter 2.5x10^-10 meters, determine the fraction of the volume found in part (a)...

    Maximum height of a projectile

    Prove that the maximum height of a projectile H, divided by the range of the projectile, R, satisfies the relation H/R = 1/4 tan. I have no idea how to do this

    How fast is the shell moving when it hits the rocks?

    Seagulls are often observed dropping clams and other shellfish from a height to the rocks below, as a means of opening the shells. If a seagull drops a shell from rest at a height of 14m, how fast is the shell moving when it hits the rocks? X= 1/2 gt^t i got 1.68945 secs do I round off to...

    Calculating Average Acceleration of a 747 Airplane

    A 747 airliner reaches its takeoff speed of 173 mi/h in 35.2s. What is the magnitude of its average acceleration? (77.3341 m/s)/(35.2 s) = 2.20 m/s^2 I am wondering did I do it correctly?

    Find the area of the resulting slick homework

    Suppose 1.0 cubic meter of oil is spilled into the ocean. Find the area of the resulting slick, assuming that it is one molecule thick, and that each molecule occupies a cube 0.50 micrometer on a side. I do not get this problem at all how do u start please help? sorry i meant micro

    What are the powers required for dimensional consistency in a simple pendulum?

    T= 2(3.14) L^(P) g^(q) T=(L)^p (L/T^2)^q T=(L)^(1/2)(L/T^2)^(-1/2) T=(L)^(1/2)(T^2/L)^(1/2) T=(T^2)^(1/2) T=T

    What are the powers required for dimensional consistency in a simple pendulum?

    The period T of a simple pendulm is he amount of time required for it to undergo one complete oscillation. If the length of the pendulm is L and the acceleration of gravity is g, then T is given by T=2(3.14)L^(P)g^q Find the powers p and q required for dimensional consistency.
