Elemental analysis of a compound containing carbon, hydrogen, nitrogen, and oxygen gave the following mass percentages for each element: C: 42.36% H: 3.555% N: 16.47% O: 37.62% The <em>molar mass</em> of the compound is Molecular formula = C6H14N2O2 Consider the total mass of the compound =100g Then mass of carbon = 49.30 g Mass of hydrogen = 9.653 g Mass of nitrogen = 19.16 g Mass of oxygen = 21.89 g Molar mass of carbon = 12.0 g/mol
<h3>What is
molar mass ?</h3>
In chemistry, the molar mass of a chemical compound is determined by dividing its mass by the molecular weight of the component that makes up the sample. The molar mass of a substance is a bulk attribute rather than a molecular one. The compound's molar mass is an average over numerous samples, which frequently have different masses because of isotopes. A terrestrial average and a function of the relative abundance of the isotopes of the constituent atoms on Earth, the molar mass is most frequently calculated using the standard atomic weights. For converting between a substance's mass and amount in bulk amounts, the molar mass is the proper unit.

Yes, i believe that it can have a physical change but it is most likely chemical.
Answer is 38/3 or 12.67
3x=38
x=38/3
therefore answer is the one mentioned above
Answer:
it would most likely occur
———————————————————————————————————————
Across a semi-permeable membrane that separates solutions of different concentrations
———————————————————————————————————————
this is because osmosis is the ‘net’ movement of molecules from a ‘region’ of ‘higher concentration’ to a ‘region’ of ‘lower concentration’ ‘down the concentration gradient’.
The isotopes of the same element in the given options are 21/10 and 22/10 (option A and B).
<h3>What is an isotope?</h3>
Isotopes are two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.
The above definition shows that atoms of isotopes will have the same atomic number but a different mass number.
Isotopes of the same elements have different number of neutrons and this causes the difference in mass numbers.
According to this question, 21/10 and 22/10 are isotopes of the same element because they have the same atomic number.
