What is the ratio of empirical formula to molecular formula of benzene?
Answer Expert Verified In Benzene C6H6 there are six carbons and six hydrogen atoms. The ratio of empirical formula is 6:6 which results in 1:1, which is CH represented as empirical formula and the formula mass of CH is (12+1), which is equal to 13g/Mol
What is the ratio of empirical formula?
An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well. Thus, H2O is composed of two atoms of hydrogen and 1 atom of oxygen. Likewise, 1.0 mole of H2O is composed of 2.0 moles of hydrogen and 1.0 mole of oxygen
What is the molecular mass of benzene?
78.11 g/mol
What is the empirical formula of a hydrocarbon with 75% carbon and 25% hydrogen by mass?
CH4
How does a molecular formula differ from an empirical formula?
The empirical formula simply states the ratios of the elements that make up the molecule, while molecular formulas specify the amounts of each element exactly, not just giving the ratio.
What fraction of pentane c5h12 by weight is carbon?

|---|---|---|
| Hydrogen | H | 16.764% |
| Carbon | C | 83.236% |
What is the empirical formula of a compound that contains 30.4% nitrogen and 69.6% oxygen by mass?
Moles of nitrogen=30.4⋅g14.01⋅g⋅mol−1=2.17⋅mol. Moles of oxygen=69.6⋅g15.999⋅g⋅mol−1=4.35⋅mol. And we divide thru by the SMALLEST molar quantity to get an empirical formula of NO2 ……….
What is the empirical formula of a compound which is 60.3% C and 39.7% H?
Steps
| 1 | Find the empirical formula of a compound that has 60.3% of Carbon (C), 39.7% of Hydrogen (H). |
|---|---|
| 6 | Divide by fractional component of each mole value: C=1. H=9./td> |
| 7 | Round to closest whole numbers: C=1, H=9 |
| 8 | Combine to get the empirical formula: CH9 |
