### Can't quite get the answer right

Posted:

**Mon Oct 22, 2018 7:41 pm**For question 1.39 in the 6th edition

I've been having serious issues getting the correct answer while using De Broglie's Equation. The conversions I've been using is the given 1 ounce = 28.3 grams, 1609 meters = 1 mile and 60 sec = 1 hour. The answer supplied at the back of the textbook lists it as 1.1 x 10^-34 m and I end up with 1.8 x 10^-36 m.

I've linked an image of my work for a visual; it also contains the text of the question.
