I am having actually a tiny trouble through a inquiry on a pre-lab assignment: when 0.422 g the phosphorus is burned, 0.967 g that a white oxide is obtained. Determine the empirical formula the the oxide.

You are watching: When 0.422 g of phosphorus is burned

The means I set it up was:

0.422g ns = 1mol P/30.97 = 0.01363

0.967g O = 1mol P/16.00 = 0.06044

I divided each by 0.01363 and got:

P = 1 ; O = 4.43

I understand I have to make castle both whole numbers, however no issue how numerous times I've double both values to shot to make O a whole number it didn't job-related out so ns feel prefer I forgot a step and also need part guidance.

You can round the 4.43 under to 4.

No friend can't.

The very same principles use to this together if you to be doing empirical formula because that a hydrocarbon. You need to multiply by an essence to obtain as close come a whole number as feasible (usually in ~ +/- 0.1). Copy it doesn't always work. What happens if you multiply by 3? through 4? by 5?

Remember that everything you main point the oxygen by, you must multiply the phosphrous

That's a little of a leap, to be honest, in any type of event.
