Question

How many molecules are there in 7.27 miles of ammonia?

Answer 1

Answer:

43.78 X 10^23

Explanation:

1 mole of NH3 has 6.023×10^23 molecules according to avogadro's principle

therefore, 7.27 moles = 6.023×10^23 X 7.27

= 43.78 X 10^23

Answer 2

Hey There!

To solve this question remember that 1 mole of ammonia is equal to 17G of ammonia.

Using that, we first multiply 17 by 7 = 24

Then we multiply 7 by .27 = 1.89

Finally, taking those and adding them together gives you the answer...

25.89 grams :)
