(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?

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)...

Are there any organisms that are almost all restriction endonucleases isolated from?

what happens to a projectile at its max heights ?

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

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...

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?

help please?

help please?

thank you very much

r= ((3.1416)(5E5)) = 1.5708E6 m^2 Like this? Because in the back of the book the answer is 2.0E6 m^2

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

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

So then it would be T=(L)^1/2(L/T^2)^(-1/2)

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.
