Very good question, I can easily answer that for you if it has 3 moles of ethane contains 6 mole of carbon atoms. so that means 3 moles of ethane contains 18 mole of hydrogen atoms.
Have a blessed day and God bless.
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...
<u>25.89 grams :)</u>

Answer:
P4Se3
Explanation:
Applying the Law of Conservation of Mass:
(133 mg total) - (45.8 mg P) = 87.2 mg Se
Dividing by the molar mass,
Phosphorus:-(45.8 mg P) / (30.97376 g P/mol) = 1.4786 mmol P
Selenium:-(87.2 mg Se) / (78.96 g Se/mol) = 1.1044 mmol Se
Divide by the smaller number of millimoles:
(1.4786 mmol P) / 1.1044 mmol = 1.339
(1.1044 mmol Se) / 1.1044 mmol = 1.000
multiply by 3, to get a whole number interger. then round to the nearest whole numbers to find the empirical formula.
Therefore the empirical formula is P4Se3
