What is the percent nitrogen by mass in ammonium carbonate?
Answer Expert Verified Ammonium carbonate has a molar mass of 96.08 grams per mole. There are two nitrogen atoms in ammonium carbonate which is equal to 28.02 grams per mole. Divide the molar mass of nitrogen to the ammonium carbonate, 08 x 100, we get 29.16wt% nitrogen.

How many atoms are in 0.35 moles carbon?
In , there 1 atom of carbon and 2 atoms of oxygen. So, the total number of atoms in are, 3. As, 1 mole of contains number of atoms. So, 0.35 mole of contains number of atoms.
Why is the mole such a large number?
The mole designates an extremely large number of units, 6.× 1023. Avogadro proposed that equal volumes of gases under the same conditions contain the same number of molecules, a hypothesis that proved useful in determining atomic and molecular weights and which led to the concept of the mole.
Why do we need the mole?
The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. However, the mole allows a chemist to work with amounts large enough to use.
How can you apply the concept of mole in real life?
In chemistry, the mole is a unit used to talk about atoms. It is similar to other units we use everyday. For example, you might walk into the local doughnut shop and order a dozen doughnuts. In doing so, you know that you will get 12 of these snacks and the clerk knows to give you 12.
What weighs more a mole of feathers or bricks?
Keep in mind that not everything weighs the same if you have a mole of it. A mole refers to the number of particles you have, not the mass. If you had a mole of feathers and a mole of bricks, you would have the same number of feathers and bricks but they would weigh completely different.
Which is heavier a pound of feathers or a pound of bricks?
So this question is kinda tricky, But the answer is that they weigh the same. Because it is already mentioned that a feather weighs 1 pound and so a brick also weighs 1 pound. So, their weigh should be equal but there might be more feathers in 1 pound.
Why did chemists create the mole?
Because atoms, molecules, and other particles are all extremely small, you need a lot to even weigh them, so that’s why chemists use the word “mole.” Keep in mind that not everything weighs the same if you have a mole of it. A mole refers to the number of particles you have, not the mass.
Which would weigh more a mole of feathers or a mole of gold?
So a pound of feathers weighs 453.59 grams approximately and a pound of gold weighs 373.24 approximately. So a pound of feathers weighs more then a pound of gold.
Which is heavier a ton of gold or a ton of silver?
Which is heavier a ton of gold or a ton of silver? They are equal as they both weigh a ton.
