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
3.00 moles of NO2 have a mass of?
138g
How many moles are in 25.6 g of NO2?
Molecular mass of nitrogen dioxide, NO2 = 14.0+2(16) = 46.0Amount of NO2 = 25.6/46.0 = 0.557molThere are 0.557 moles of NO2 in a 25.6g sample.
What mass of NO2 is formed when NO reacts with 384g O2?
1 to 1 ratio so 384g of NO2 is produced
Molar mass of no2?
N= 7 O = 16 Molar mass = 39

4) How many moles are in 1.18 g of NO2?
Molar mass NO2 = 46.0 g/mole1.18 g NO2 x 1 mol NO2/46.0 g = 0.0257 moles NO2 (to 3 significant figures)
How many moles are in 25.6 g of NO2?
Molecular mass of nitrogen dioxide, NO2 = 14.0+2(16) = 46.0Amount of NO2 = 25.6/46.0 = 0.557molThere are 0.557 moles of NO2 in a 25.6g sample.

Molar mass of no2?
N= 7 O = 16 Molar mass = 39
What is the molar mass of nitrogen dioxide nearest gram?
NO2 is 46 molar mass
What is the molar mass of Co(NO2)3?
196.9497 g/mol
How many moles of no2 are present in 138.08?
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.
A gas contains NO2 molecules at 44C What is the average speed of the molecules and the mass of a NO2 molecule is 7 point 64 times 10 to the negative 26 kg?
ABigNumber.
What is the molar mass The formula for nitrogen dioxide is NO3?
46.0055. The formula for Nitrogen dioxide is NO2
What is the mass of 99.01of NO2 at STP?
If 99,01 is a mass in g this remain unchanged and not dependent from pressure in a closed system.The molar mass nitrogen(II) oxide is 30,01 g.
