Calculate the percent nitrogen by mass in chlorophyll C55H72MgN4O5?

You would first calculate the atomic mass of chlorophyll, which would be 892.9 g/mol (I did not calculate this out, but looked it up b/c of the complexity of the calculation). Then find the molar mass of the Nitrogen part of the chlorophyll (4 mol *14.01 g/mol=56.04 grams). Then, take 56.04 grams/892.9grams= .06276, or 6.276% nitrogen by mass


What is the mass of 2.50 X 104 molecules of nitrogen gas?

To calculate the mass of 2.50 x 10^4 molecules of nitrogen gas, you need to know the molecular weight of nitrogen. The molar mass of nitrogen (N2) is approximately 28.02 g/mol. Using this information, you can then calculate the mass of 2.50 x 10^4 molecules of nitrogen gas.


What is the mass in grams of 5.97 x 1027 atoms of nitrogen?

To find the mass of 5.97 x 10^27 nitrogen atoms, calculate the molar mass of nitrogen (14.01 g/mol) and then multiply by the number of atoms. Using Avogadro's number (6.022 x 10^23 atoms/mol), you would find that the mass of 5.97 x 10^27 nitrogen atoms is approximately 1.68 grams.


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 many atoms of nitrogen are in 10g of NH4NO3?

One mole of NH4 (ammonium) has one mole of nitrogen atoms and four moles of hydrogen atoms, for a total of five moles of atoms. Multiply by Avogadro's Number to convert moles of atoms to atoms.

If the atomic weight of nitrogen is 14.01 what is the mass of the nitrogen atoms in one mole of cadmium nitrate Cd(NO3)2?

To calculate the mass of nitrogen atoms in one mole of cadmium nitrate, we first need to determine the molar mass of Cd(NO3)2. The molar mass would be the sum of the atomic weights of Cd, N, and 6 O atoms in the formula. After adding these atomic weights, we can find the mass of nitrogen atoms in one mole of cadmium nitrate by multiplying the molar mass by the ratio of nitrogen atoms in the formula.


How do you calculate the number of atoms in 6980 of nitrogen?

To calculate the number of atoms in 6980 grams of nitrogen, you would first convert the mass of nitrogen to moles using the molar mass of nitrogen (~14 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. Overall, the calculation would be 6980 grams of nitrogen * (1 mol / 14 grams) * (6.022 x 10^23 atoms / 1 mol).


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.


How do you calculate atoms nitrogen and oxygen?

To calculate the number of atoms in a sample of nitrogen or oxygen, you first need to know the amount of substance in moles (given in the question or calculated from the sample's mass and the molar mass of the element). Then, you can use Avogadro's number (6.022 x 10^23) to convert moles into the number of atoms. This value represents the number of atoms in one mole of a substance.


What is the mass of 3.01.1021 atoms of nitrogen?

To find the mass of 3.01 x 10^21 atoms of nitrogen, you would first calculate the molar mass of nitrogen (14.01 g/mol). Then, convert the number of atoms to moles by dividing by Avogadro's number (6.022 x 10^23), and multiply by the molar mass to get the mass. The mass of 3.01 x 10^21 atoms of nitrogen would be approximately 63.5 grams.


How many atoms of nitrogen are in 20g of NH4NO3?

To find the number of atoms of nitrogen in 20g of NH4NO3, first calculate the molar mass of NH4NO3 (80.043 g/mol). Next, divide the mass of NH4NO3 by its molar mass to find the number of moles (0.2496 mol). Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23) to determine the number of atoms of nitrogen (1.50 x 10^23 atoms).


What is the molar mass of a substance that is 23.4 percent N by mass and one molecule contains 5 nitrogen atoms?

The gram atom mass of 5 nitrogen atoms is 5 times the gram atom mass for a single nitrogen atoms, which can be found, in a periodic table or other reference, to be 14.007. Therefore the gram atom mass of 5 N atoms is 5 X 14.007 = 70.035. 23.4 % = 0.234. From the problem statement, the unknown molar mass M of the substance obeys the relationship 0.234 M = 70.035, or M = 299, to the justified number of significant digits.

What mass of nitrogen is contained in 0.468 g of caffeine?

To find the mass of nitrogen in 0.468 g of caffeine, first determine the molar mass of caffeine, which is 194.19 g/mol. Next, calculate the mole ratio of nitrogen in caffeine, which is 3 nitrogen atoms per 1 molecule of caffeine. Then, convert 0.468 g of caffeine to moles, and finally to mass of nitrogen. The mass of nitrogen contained in 0.468 g of caffeine is approximately 0.024 g.


Why is carbon dioxide heavier than nitrogen?

The density of a gas is proportional to its molecular mass. Nitrogen (N2) contains 2 nitrogen atoms each with a mass of about 14 AMU (atomic mass units) for a total molecular mass of about 44. Carbon dioxide (CO2) contains 2 atoms of oxygen, each with a mass of about 16 AMU and 1 carbon atom with a mass of about 12 AMU for a total mass of 44.
