Atomic Mass ratio for O : N is 15.9994 : 14.0067 .
So it takes 14.0067/15.9994 moles of Oxygen to have the same mass as one mole of nitrogen. This is valuated at 0.8754516 to 1.00000

What isotope X of a particular element has an atomic number of 7 and a mass number of 15 therefore?
You are talking about a natural isotope of nitrogen i.e Nitrogen-15 which has atomic number same as nitrogen (7) ans mass number 1 greater than standard nitrogen (i.e 15 as Nitrogen's mass no. is 14). Nitrogen-15 has i neutron more than standard nitrogen
In the electron charge to mass experiment if the electron is replaced by a proton or neutron would the charge to mass ratio value still be the same why or why not?
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
What mass of oxygen contain same number of molecule as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
Why does the density of a substance not change with the sample size?
Density = mass / volume As sample size increases, both mass and volume increase in the same ratio.
What information would be requierd to determine the mass number of nitrogen?
You would need to know how many protons and neutrons are in the nucleus of a particular isotope of nitrogen. The number of protons, which is its atomic number, will always be the same, no matter which isotope is given, but the number of neutrons differs with different isotopes. For example, one isotope of nitrogen has 7 neutrons. To determine its mass number, find nitrogen on the periodic table, and you will see that its atomic number is 7. So this isotope of nitrogen has 7 protons. Now, add the 7 neutrons to the 7 protons, and you get a mass number of 14 for this isotope of nitrogen, which is called nitrogen-14. (Isotopes are named by their mass numbers.) Another isotope of nitrogen has 8 neutrons. Add the 8 neutrons to the 7 protons (atomic number), and you get a mass number of 15 for this isotope of nitrogen, called nitrogen-15.
What is the gram atomic mass of nitrogen?
gram atomic mass (or atomic mass) of nitrogen (N) is 14 u.
Name two elements have the same mass numbers?
No elements have the same average mass, but some isotopes are the same mass as other elements, For example Carbon-13 (an isotope of carbon) has the same mass as nitrogen-13 (which is also an isotope of nitrogen).
Two masses are in the ratio 1 4 what is the ratio of their inertia?
The ratio is the same. Inertia depends entirely on mass.
Why is a mass spectrometer incapable of distinguishing between ions?
They have the same mass/charge ratio.
What is the atomic mass number for nitrogen?
The atomic weight is14.00674
What isotope X of a particular element has an atomic number of 7 and a mass number of 15 therefore?
You are talking about a natural isotope of nitrogen i.e Nitrogen-15 which has atomic number same as nitrogen (7) ans mass number 1 greater than standard nitrogen (i.e 15 as Nitrogen's mass no. is 14). Nitrogen-15 has i neutron more than standard nitrogen
Who first recognized that the ratio of the number of atoms is the same as the ratio of the masses that combine?
The first person to recognize the total ratio of the number atoms is the same as the total ratio of the ratio of the mass is JOHN DALTON.This is also called the "Law of Multiple Proportion"
What is the mass ratio if the volume ratio is 2 to 3?
The same 2 to 3 because the mass is directly proportional to the volume. Recall the relationship Mass = volume x density. Here density remains constant
What is the ratio of nitrogen atoms N to oxygen atoms O in a compound with the formula N2O5 is the same as the compound NO2?
These ratios are not identical. In N2O5 the ratio is 2/5. In NO2 the ratio is 1/2.
Is oxygen 16 and nitrogen 16 isotopes of each other?
No, they are isotopes with the same atomic mass. But they are isotopes of different elements and so are very different from on another. For example nitrogen-16 and nitrogen-14 are isotopes of the same element.
What mass of hydrogen contains the same number of atoms as 8.65 g of nitrogen?
0,617 g
When mass nd volune increases does destity stay the same?
If they both change in the same ratio, yes. Otherwise, no.
