How many m3 nitrogen in 1 kilogram?
To answer this you need to find out the mass of 1m (or 1 dm) of nitrogen.
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.
How do you calculate the number of neutrons an element has in its nucleus?
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
How much nitrogen is in 7.5 grams of ammonia?
First you need to find the atomic masses of each element involved in the compound NH3, and add them up to find the total molecular mass of ammonia.Nitrogen = 14.0 gramsHydrogen = 1.01 × 3 atoms = 3.03 grams----------------------------------------------------Ammonia = 17.03 gramsThen you take the mass of nitrogen in one molecule and divide it by the total mass to find the percent composition.14.0 grams Nitrogen ÷ 17.03 grams Ammonia = .822 = 82.2% nitrogen in ammoniaThen you simply need to take 82.2% of 7.5 grams to find how much nitrogen is in that particular amount.82.2% × 7.50 = 6.17 grams of nitrogen in 7.50 grams of ammonia
Do you need atomic number to find atomic mass?
no you do not need to know the atomic number, as that only equates to the number of protons in an atom. Most periodic charts will show you the atomic mass of an element
What is the need of fixing atmospheric nitrogen find out the various ways by which atmospheric nitrogen is fixed?
Why does atmospheric nitrogen need to be converted?
What information would you need to find the atomic mass?
atomic number and its squrare
What is the number of neutorns in nitrogen?
To find the number of neutrons, all you need to do is round the atomic weight to the nearest whole number. The atomic weight of nitrogen is 14.007, or about 14. The atomic weight is basically the average number of particles in an atom's nucleus. What particles are located in the nucleus?? The protons and the neutrons. So, all you have to do is subtract the number of protons from the atomic weight and you get the neutrons!!HERE'S HOW YOU DO IT:Nitrogen's atomic # = 7Nitrogen's atomic mass = 14Neutrons + Protons = Atomic Mass so... 14-7=7The number of neutrons is 7.
To find the number of neutrons is an isotope start with the mass number and what?
The mass number of an isotope is the number of neutrons and protons in the isotope, let this be p +n = (mass number). To find the number of neutrons you need the atomic number (number of protons), let this be p. You then subtract the two: mass number - atomic number = no. of neutrons p + n - p = no. of neutrons = n
How do you find the mass of hydrogen?
Look on a periodic table. If you have different isotopes then you need to multiply the mass number and atomic number and then find the average of them and you'll have the average atomic mass which is the same as on the periodic table. The location of the mass number on a periodic table depends but it's normally the one with a decimal.
How do you Calculate the mass percent composition of nitrogen oxide?
There is a formula to calculate the mass percent composition (which can be found in your reference table T for chemistry students)mass of element----------------------- X 100gram-formula massFirst of all you need to find the gram formula mass:2 N atoms= 2(14.0 amu) = 28.0 amu6 O atoms= 6(16.0 amu)= 96.0 amuthen add together124 amuThen plug in with the formula:(2X 14)----------- X 100% = 22.58% = % Nitrogen124 amuTo check to make sure the answer is correct the percentages of the individual elements must addd up to 100%. So you would then need to find the % oxygen. which is 77.41%. So in this case 77.41%+ 22.58%is 99.99% which can be rounded to 100% so in this case the answer is correct.
How do you find the mass number if you have the atomic number of an isotope?
Mass number is the sum of protons and neutrons in the nucleus of the atoms of a particular isotope. The atomic number is the number of protons, so you would also need to know the number of neutrons. You could not determine the mass number from the atomic number alone.
