The name diphosphorus pentoxide indicates that there are (exactly) five oxygen atoms in each molecule. Therefore, 3.45 mol contains 17.25 mol of oxygen atoms. However, at standard temperature and pressure, oxygen exists in the form of divalent molecules. Therefore, if the question pertains to oxygen under such conditions, the correct answer is 8.62 mol, to the justified number of significant digits.
The molecular formula of sulphur trioxide is SO3. What is the mass of oxygen present in 20 g of sulphur trioxide? (Relative atomic mass: S = 32; O = 16) need help
Dicyclohexyl chemical formula is C12H22 and the molecular weight is 166,3031 (not 200).
To determine the molar mass without knowing the molecular formula, you can use techniques such as mass spectrometry, which measures the mass-to-charge ratio of ions, allowing you to infer the molar mass of the compound. Additionally, you can perform elemental analysis to assess the composition of the compound and then calculate the molar mass based on the known atomic masses of the elements present. These methods can provide an approximate molar mass even in the absence of the exact molecular formula.

To find the molecular formula from the empirical formula, we need to know the molar mass of the empirical formula. In this case, the empirical formula's molar mass is 88. To find the molecular formula, we divide the given molecular mass (176) by the empirical formula's molar mass (88) to get 2. This means the molecular formula of Vitamin C is twice the empirical formula, so the molecular formula is C6H8O6.
The molecular formula of sulphur trioxide is SO3. What is the mass of oxygen present in 20 g of sulphur trioxide? (Relative atomic mass: S = 32; O = 16) need help
The molar mass of sulfur trioxide (SO3) is approximately 80.06 grams per mole.
The atomic (molecular) weight of a substance is its molar mass.
The molar mass of sulfur trioxide (SO3) is approximately 80.07 grams per mole. This means that a single sulfur trioxide molecule has a mass of about 80.07 atomic mass units.
The foumula for diphosphorus dioxide is P2 O2 by Calpio
molar mass of unknown/molar mass of empirial = # of empirical units in the molecular formula. Example: empirical formula is CH2O with a molar mass of 30. If the molar mass of the unknown is 180, then 180/30 = 6 and molecular formula will be C6H12O6
The empirical formula NH2Cl has a molar mass of 51.5 g/mol, so the molecular formula can be determined by finding the ratio of the molar mass of the molecular formula to the molar mass of the empirical formula. The molecular formula of the compound is therefore NH2Cl2.
Sulfur Trioxide has a molar mass of 80.0632 grams per mole. Therefore, 6.11 moles of Sulfur Trioxide is 489.186152 grams (without significant figures). With significant figures that would be 489 grams.
The molar mass of a compound is the same as its molecular weight, which is 58.44 g/mol.

To find the molecular formula, you need the empirical formula and molar mass. If the molar mass is 160 plus 5 grams per mole, the molecular formula cannot be determined without additional information about the empirical formula's molar mass relationship.
Dicyclohexyl chemical formula is C12H22 and the molecular weight is 166,3031 (not 200).
