How many moles of molecules are in 25.5g of NO2?
Determine the molar mass of NO2 using the subscripts in the formula and the atomic weights in grams from the periodic table. 1 mole NO2 = (1 x 14.0067g N) + (2 x 15.9994g O) = 46.0055g NO2 Calculate the moles NO2 by dividing the given mass by the molar mass. 25.5g NO2 x (1mol NO2/46.0055g NO2) = 0.554mol NO2
Molar mass of no2?
The molar mass of NO2 (nitrogen dioxide) is approximately 46 grams per mole.
The formula for nitrogen dioxide is NO2 What is the molar mass of nitrogen dioxide to the nearest gram?
The molar mass of nitrogen (N) is approximately 14 grams/mole, and the molar mass of oxygen (O) is approximately 16 grams/mole. Therefore, the molar mass of nitrogen dioxide (NO2) is 14 + (2*16) = 46 grams/mole to the nearest gram.
What is the molecular formula for the compound containing 30.4 percent nitrogen and 69.6 percent oxygen by mass and having a molar mass of 92.0 g?
Assume those percentages as mass. Find moles. 30 grams Nitrogen (1 mole N/14.01 grams) = 2.141 moles ( call it 2 ) 70 grams oxygen (1 mole O/16.0 grams) = 4.4 moles ( call it 4 ) smallest mole number is 1 in formula and divide larger number by it 2/4 = 2 so.............. NO2 nitrogen dioxide is the empirical formula
What nitrogen oxides have the same empirical formula?
The nitrogen oxides that have the same empirical formula are nitric oxide (NO) and nitrogen dioxide (NO2). Both have a 1:1 ratio of nitrogen to oxygen atoms.
What is the molar mass The formula for nitrogen dioxide is NO3?
46.0055. The formula for Nitrogen dioxide is NO2
Does no and no2 have the same empirical formulas?
No: The formula NO shows equal numbers of nitrogen and oxygen atoms in the compound, but the formula NO2 shows twice as many oxygen atoms as nitrogen atoms.

What is the empirical formula stannic nitrite?
The empirical formula of stannic nitrite is Sn(NO2)4.
What is the empirical formula for nitrogen dioxide?
The empirical formula for nitrogen dioxide is the same as its molecular formula - NO2. See related question below for more details on how to find empirical formulas.
What is the molar mass of nitrogen dioxide nearest gram?
The molar mass of nitrogen dioxide (NO2) is approximately 46 grams per mole.
Molar mass of no2?
The molar mass of NO2 (nitrogen dioxide) is approximately 46 grams per mole.
The formula for nitrogen dioxide is NO2 What is the molar mass of nitrogen dioxide to the nearest gram?
The molar mass of nitrogen (N) is approximately 14 grams/mole, and the molar mass of oxygen (O) is approximately 16 grams/mole. Therefore, the molar mass of nitrogen dioxide (NO2) is 14 + (2*16) = 46 grams/mole to the nearest gram.
If the formula for nitrogen dioxide is NO2 what is the molar mass of nitrogen dioxide to the nearest gram?
The approximate molar mass is about 46 g/mol (46.01 g/mol). You can estimate this by using the atomic mass numbers of nitrogen (8) and oxygen (16). N = 14.006 ~ 14 O = 15.994 ~ 16 14 + 2 (16) = 46
4) How many moles are in 1.18 g of NO2?
To find the number of moles in 1.18 g of NO2, you need to divide the given mass by the molar mass of NO2. The molar mass of NO2 is approximately 46 g/mol. So, 1.18 g / 46 g/mol = roughly 0.026 moles of NO2.
