What is the atomic mass of Nitrogen and oxygen?
since the total is 68 we will subtract 42 to find the amount of oxygen which is 26. u can do this one of two ways 1- 42:26 is the ratio of nitrogen to oxygen in the following compound, so no it is not nitrous oxide because 42/26 = 1.62 while 7/4 = 1.75 close but not it
Why the magnesium have a atomic mass of 24?
The atomic mass of magnesium is 24 because it is a weighted average of the isotopes of magnesium found in nature. The most abundant isotopes of magnesium are Magnesium-24, Magnesium-25, and Magnesium-26, with natural abundances of approximately 78.99%, 10.00%, and 11.01% respectively. The atomic mass takes into account both the mass and relative abundance of each isotope.
What is the molecular mass of O2?
The molecular weight of oxygen is 16. Its atomic symbol is O and atomic number is 8. It is a gas in its natural state.
Atomic mass of oxygen?
The atomic mass of oxygen is approximately 16.00 atomic mass units (amu). This value represents the average mass of an oxygen atom, taking into account its different isotopes and their natural abundance.
How many protons and newtrons are there in16O8 and 56Fe26?
The atomic number of Oxygen is 8 and hence it has 8 protons and 8 electrons. Oxygen has a mass number of 16. The number of neutrons is obtained my subtracting the number of protons from the mass number, i.e., 16-8 = 8. Therefore, Oxygen has 8 protons as well as 8 neutrons. Now, Fe (Iron) is an interesting element. It has many isotopes. So, the exact number of neutrons is an estimated value. However, since the mass number has been given (56) we have to only determine the number of neutrons for this isotope of Iron. The number of protons is the same as the atomic number i.e., 26. The number of neutrons is obtained by subtracting the number of protons from the mass number , i.e., 56-26 = 30. Therefore, according to the given data, Oxygen has 8 protons and 8 electrons. Iron has 26 protons and 30 neutrons.
What is the mass of oxygen 16?
If you really meant to ask "What is the mass defect of oxygen-16," this is how you do it. mass defect = # of protons x mass of one proton + # of neutrons x mass of one neutron - mass of the nucleus The atomic number of oxygen-16 is 8, so there are 8 protons. The mass of one proton is approximately 1.0073 amu. The Atomic Mass of oxygen-16 is 16, so there are 8 neutrons in oxygen-16. (Atomic mass of 16 minus atomic number of 8 = # of neutrons in oxygen-16.) The mass of one neutron is approximately 1.0087 amu. The mass of the nucleus of oxygen is 16. Now substitute the values into the "mass defect" equation: mass defect = 8x1.0073+8x1.0087-16=approximately 0.128 amu.
What is the mass number of a magnesium atom with 14 neutrons?
The mass number is the sum of protons and neutrons in an atom. Since magnesium has 12 protons, a magnesium atom with 14 neutrons would have a mass number of 26 (12 protons + 14 neutrons = 26 mass number).
The mass of one oxygen molecule is?
Number of protons in oxygen atom: 8Mass of one proton = 1.67262158 x 10-27 KgMass of protons in one oxygen atom = 1.338097264 x 10-26 KgMass of one neutron: 1.674927293 x 10-27 KgMass of neutrons in one oxygen atom: 1.33994183 x 10-26 (for 8 neutrons)Mass of one oxygen atom: 2.67803909 x 10-26 (protons + neutrons).Now double the mass of one oxygen atom to get the mass of one molecule.Therefore, mass of a single oxygen molecule is 5.35607818 x 10-26 kg.
