Problem 7:

a) In chemistry and the relationship between mass moles is introduced. =

Where

n = number of moles of a substance m = mass of the substance

NW = molecular weight (molar mass) of the substance

Create a required two vector inputs (mass and molecular weight) and returns the corresponding number of moles function m-file called moles. as

It provides input vector will be necessary to use the function meshgrid in their calculations. Test function for compounds shown in the following table,

for masses from 1 to 10 g:

Molecular Weight Compound Benzene 78 115 g / mol Ethyl alcohol 46.07 g / mol Tetraflouroetano 102.3 g / mol Its result should be an array of 10 x 3.

b) A rocket is launched vertically. At time t = 0, the rocket motor is turned off. At that time, the rocket has reached a height of 500 meters and rises with a speed of 125 meters per second. Then gravity takes over. Rocket height as a function of time is ℎ () = - 92.8 2 + 125 + 500> 0

Create a function called high time to accept as input and returns height

rocket. Use their role in their solutions to parts b and c. Plot the height against time to time from 0-30 seconds. Use a

increased 0.5 seconds on its vector time. Find the time when the rocket starts to fall back to the ground.
