Chem question? Heisenberg uncertainty principle?

[karly180]

a) Use the Heisenberg uncertainty principle to calculate Δx for an electron with Δv = 0.670 m/s.

b) By what factor is the uncertainty of the (above) electron's position larger than the diameter of the hydrogen atom?
(Assume the diameter of the hydrogen atom is 1.00×10-8 cm.)

c) Use the Heisenberg uncertainty principle to calculate Δx for a ball (mass = 152 g, diameter = 8.75 cm) with Δv = 0.670 m/s.

d) The uncertainty of the (above) ball's position is equal to what factor times the diameter of the ball?

Okay, so for for part a) What do you know about the uncertainty principle and how would you use it in an equation?
