### What mass of oxygen contain the same number of molecules 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 10 g nitrogen gas contain the same number of molecules as 10 g of carbon monoxide?

These compounds have equal molar masses.

### If two atoms of nitrogen completely react with six atoms of hydrogen to form two molecules of ammonia which best describes the number of hydrogen atoms present in the two molecules of ammonia?

Two molecules of ammonia contain 6 hydrogen atoms.

### Which two samples of gas at STP contain the same total number of molecules?

Theoretically, if they have the same volume, all samples will contain the same number of molecules.

### What molecule is nitrogen found in?

Nitrogen is found in a number of molecules but perhaps most famously it is found in the DNA molecule.

### Why does 10g of nitrogen gas contain the same number of molecules as 10g of carbon molecules?

No, they do NOT contain the same number of particles (either molecules N2 or atoms C): there molecular or atomic mass is different.Look at this:10g N2 / 28 (g/mole N2) x 6.022x1023 (molecules N2/mole N2) = 2.15 x1023 molecules N210g C / 12 (g/mole C) x 6.022x1023 (atoms C/mole C) = 5.02 x1023 atoms C

### Why oxidation number of Carbonmonoxide is zero?

is not an ion. So oxidation number of total molecule is zero.

### How would you know from looking at the periodic table that O molecules are smaller than nitrogen molecules?

Oxygen and nitrogen are in the same period of the table, and within a period, atomic radius decreases with increasing atomic number. Oxygen has a higher atomic number than nitrogen. From the periodic table alone, there is no direct information about the size of the molecules, but both these elements form diatomic molecules, and it is reasonable that molecules formed from the same number of atoms will have sizes in the same order as the sizes of the atoms.
