Determing if a number is Even or Odd?

If we have an odd number n, then we multiply it by 3 and add one (n*3+1), we know we will get an Even number p. How can one determine how many times p can be divided by two before it is odd again?

Another way of asking the same question. if we have (n*3+1)/(2 to some power), how can we determine if the number produced will be odd or even depending on the chosen n and the chosen power of two?

Is there a way to symbolize divide by two until odd in a function?
Thanks for all the help!
