Molecules of NO2 contain covalent bonds
Assuming you mean 138.08 grams, you set up a direct proportion between the molar mass of NO2 and your given mass. NO2 comes in at 46g/mol (14+16+16), and your proportion should be 46/1=138.08/x. Solve for x to get approx. 3 moles.
The molar mass of nitrogen dioxide (NO2) is approximately 46 grams per mole.

To produce 5.00x10^22 molecules of nitrogen monoxide (NO), you need an equal number of molecules of nitrogen dioxide (NO2). With the balanced chemical equation 2NO2 + H2O โ 2NO + 2HNO3, you can calculate the mass of nitrogen dioxide needed using the molar masses of NO2 and NO.
To determine the number of molecules in 19.6 g of NO2, you first need to calculate the number of moles in the sample. Then, you can use Avogadro's number (6.022 x 10^23 molecules per mole) to convert moles to molecules.
The answer is 5,213.10 ex.23.
To find the number of molecules in 25.0 g of NO2, you can start by converting the mass to moles using the molar mass of NO2. Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
To find the number of moles, divide the number of molecules by Avogadro's number. 4.651024 molecules of NO2 divided by 6.022 x 10^23 molecules/mol equals approximately 7.72 x 10^-24 moles.
To find the number of moles of NO2 in 25.5g, you need to divide the given mass by the molar mass of NO2. The molar mass of NO2 is 46.01 g/mol. Therefore, 25.5g รท 46.01 g/mol = approximately 0.554 moles of NO2.
To determine the grams of oxygen needed to produce 4.50 moles of NO2, use the coefficients in the balanced equation. In this case, 7 moles of O2 are required to produce 4 moles of NO2. Calculate: (4.50 moles of NO2) * (7 moles of O2 / 4 moles of NO2) = 7.88 moles of O2. Finally, convert moles to grams using the molar mass of O2 (32.00 g/mol): 7.88 moles * 32.00 g/mol = 252.16 grams of O2.
There are approximately 6.022 x 10^23 gas molecules in 1 mole of NO2. This number is known as Avogadro's constant.
If the reaction had a 75% yield, 75% of the theoretical maximum amount of NO2 molecules would be produced. To calculate the number of NO2 molecules formed, you would multiply the theoretical maximum by 0.75.
To find the number of atoms in 1.3 x 10^22 molecules of NO2, we need to consider the number of atoms in each molecule. NO2 has 3 atoms (1 nitrogen and 2 oxygen). So, the total number of atoms in 1.3 x 10^22 molecules of NO2 would be 3.9 x 10^22 atoms.
