How many hydrogen atoms are contained in 175 grams of C3 H8?
Here's what I multiplied together: 175 g C3H8 x 1 mol H8 X 6.022 x 10^23 X 8 H Atoms.
Here's what I divided by 32.08 g C3 H8. Plus the usual cancelling units.
I ALMOST have the right answer. Please help. Or if you know a better way, anything would be great.
