How many nitrogen atoms would be present in 7 moles of NH42C2O4?
Your compound's chemical formula is (NH4)2Cr2O7 - so you can see that it contains 2 moles of NH4+ per mole of the salt. So in 7 moles you have 14 moles of ammonium, containing 14 moles of N atoms which means that you have (1 mole = 6,022*10^23 atoms) 14 mols * 6,022*10^23 atoms/mole = 8,43*10^23 atoms
What is the mass of nitrogen in grams?
One mole of atoms of an element is equal to the atomic mass of that element expressed in grams. Nitrogen-14 so one mole of nitrogen weighs 14 g

If a mole of atoms were spread uniformly over the surface of the Earth how many atoms would there be per square meter?
A mole of any substance contains 6.02x1023 atoms. The surface of the earth is about 510x106 km2. This surface area is the same as 5.10x1014 m2. Therefore each square meter would have (6.02x1023 atoms)/(5.10x1014 m2) atoms/m2. This reduces to 1.18x109 atoms/m2
What is the mass of nitrogen in grams?
One mole of atoms of an element is equal to the atomic mass of that element expressed in grams. Nitrogen-14 so one mole of nitrogen weighs 14 g
How many atoms are in 14 moles of cadmium?
To find the number of atoms in 14 moles of cadmium, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Therefore, there are approximately 14 x 6.022 x 10^23 atoms in 14 moles of cadmium.
What has a mass of 14 g?
1 mole of carbon-14 atoms. (probably what your instructor is looking for) More specifically, One mole of the isobar (elements with the same number of nucleons) with 14 nucleons: Be-14, B-14, C-14, N-14, O-14, F-14 are all suitable elements of which 1 mole of any of them (or a combination of all of them) will equal 14 grams. Also, any 1 mole of a molecule with a molecular weight of 14 will weigh 14 grams. An example: Methane: CH4 IFF the carbon atom is a C-10 and the hydrogens are H-1. Or half a mole of Silicon-28, and so on... Mess with your professor a bit. It's good for them. haha!
How many grams of sodium contain the same numberof atom as 15grams of magnesium?
Let us find Magnesium atoms first. 15 grams magnesium (1 mole Mg/24.31 grams)(6.022 X 10^23/1 mole Mg) = 3.72 X 10^23 atoms magnesium Now take this an drive to grams sodium 3.72 X 10^23 atoms (1 mole Na/6.022 X 10^23)(22.99 grams/1 mole Na) = 14 grams of sodium ----------------------------

What is the mass of the nitrogen atoms in one mole of cadmium nitrate?
To find the mass of the nitrogen atoms in one mole of cadmium nitrate, calculate the molar mass of cadmium nitrate (Cd(NO3)2) and then multiply it by the number of nitrogen atoms in one mole of cadmium nitrate (2 nitrogen atoms). The molar mass of cadmium nitrate is 236.41 g/mol. Therefore, the mass of the nitrogen atoms in one mole of cadmium nitrate is 28.02 g.
What is ekasilicon atomic mass?
The atomic mass of ekasilicon is 293.21 grams per mole. It contains 14 silicon atoms and 2 germanium atoms in its molecular structure.
How many moles of hydrogen atoms in C2H6?
You will need to specify the mass of C6H6 in order to calculate a number of moles. If you know the mass, the general formula is:n=m/M, where n is the number of moles, m the mass of C6H6 and M the molar mass (78.11g/moles)
