The molar mass of magnesium is 24.31 g/mol, while the molar mass of oxygen is 16 g/mol. To find the mass of 2.6 g of magnesium, you can divide 2.6 g by the molar mass of magnesium (24.31 g/mol) and multiply by Avogadro's number to find the number of moles. Similarly, you can do the same calculation for 1.6 g of oxygen and then sum up the molar masses to find the total mass.

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
Atomic mass of oxygen?
Oxygen is a non metal element. Atomic mass of it is 15.999.
What is the molecular mass of O2?
The atomic weight of oxygen is 15.9994 g/mol-1
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.
How many isotopes does magnesium Mg have?
3 tonsThe mass of Earth's Lithosphere is around 1.365 x 10^23 kg, or136 500 000 000 000 000 000 000 kg.Of this, around 2.09% is magnesium, and therefore 2.85285 x 10^21 kg is magnesium, or2 852 850 000 000 000 000 000 kg.

An isotope of iron has 26 protons and 32 neutrons what is the mass number?
An unknown element contains 24 protons, 21 electrons,and has mass number 54
What is the mass number of a magnesium atom with 14 neutrons?
The mass number is the number of protons plus neutrons. Magnesium is element number 12, so it has 12 protons. Its mass number with 14 neutrons is 12 + 14 which is 26.
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.
Atomic mass of oxygen?
Oxygen is a non metal element. Atomic mass of it is 15.999.
What element has a mass numberof 16 and atomic number of 8?

How many neutrons and protons are in Magnesium 26?
Manesium 24 has 12 electrons, protons and neutrons.
How many protons and neutrons are in Mg?
The number of protons (p+) in the nuclei of an element's atoms is the atomic number of the element. In this case, the atomic number of magnesium is 12. In a neutral atom, the number of electrons (e-) equals the number of protons. So all neutral magnesium atoms have 12 protons and 12 electrons. Isotopes of an element differ in the number of neutrons (n0).There are three stable isotopes of magnesium (Mg) identified by their mass numbers; magnesium-24, magnesium-25, and magnesium-26. The mass number is the sum of protons and neutrons in the nucleus of an atom. To determine the number of neutrons, subtract the atomic number from the mass number. (mass number - atomic number = no. of neutrons)Magnesium-24: 24 - 12 = 12; An atom of Mg-24 has 12 p+, 12 e-, and 12 n0.Magnesium-25: 25 - 12 = 13; An atom of Mg-25 has 12 p+, 12 e-, and 13 n0.Magnesium-26: 26 - 12 = 14; An atom of Mg-26 has 12 p+, 12 e-, and 14 n0.
