Compound's molecular formula?
What is the molecular compound formula of a compound that contains 42.87% carbon, 3.598% hydrogen, 25% nitrogen, and 28.55% oxygen and has a molar mass between 2010 and 2020?
Answer:
42.87 / 12.011 = 3.57 C
3.598 / 1.0079 = 3.57 H
25 / 14.0067 = 1.78 N
28.55 / 15.9994 = 1.78 O
We divide 3.57 for 1.78 =2
The formula is C2H2NO ( mass =56)
Since 2016 / 56 = 36 we multiply each number for 36 and we get
C72 H72 N36 O36Which of the following statements are true?
What is the pressure of the gas in the cylinder?
Ethene + high pressure and heated catalyst gives?
What does this suppose to tell us?
What ratio of HC03- to H2CO3 is an alkalotic pH?
Help! mole, mass?
Aspirin,paracetomol more soluble in alkaline water but codeine better into acidic water = easy separation.?
