What is the empirical formula of a compound with 40 grams carbon 6.7 grams hydrogen and 53.3 grams oxygen?
We divide thru to get, C:H:O. = 3.33:6.65:3.34 . When we divide each elemental ratio by the LOWEST number, we get an empirical formula of CH2O , i.e. near enough to WHOLE numbers.
What is the empirical formula of a compound that has found to contain 40.00\% C 6.71\% H and 53.29\% o the molar mass of the compound is 60.05 g mol?
Ernest Z. The empirical formula is CH₂O and the molecular formula is C₆H₁₂O₆. Assume we have 100 g of the compound. Then we have 40.00 g of C, 6.72 g of H, and 53.28 g of O.
What is the formula of hydrogen?
H2
It is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. It has an atomic mass of 1.00794. Hydrogen is the most abundant element in the universe and it has an atomic number of 1 . Hydrogen has a molar mass of 1 and it’s molecular formula is H2.
What is empirical formula and molecular formula?
The empirical formula of a compound gives the simplest ratio of the number of different atoms present, whereas the molecular formula gives the actual number of each different atom present in a molecule. If the formula is simplified then it is an empirical formula.
What is the empirical formula of a compound that contains 40 percent carbon?
The ratio comes out as C:H:O=1:2:1 . Thus, the empirical formula is CH2O .
Which of the following possess 40 carbon by mass?
| Element | Percentage | Relative number of atoms |
|---|---|---|
| Carbon | 40.0 | 4010=3.33 |
| Hydro gen | 6.66 | 6.661=6.66 |
| Oxygen | 53.34 (by difference) | 53.3416=3.33 |
What is the formula for oxygen?

What is the atomic mass of 40\% carbon hydrogen and oxygen?
O A compound contains 40\% carbon, 6.7\% hydrogen, and 53.3\% oxygen. 100 g of the compound will contain 40 g C, 6.7 g H and 53.3 g O. The atomic masses of C, H and O are 12 g/mol, 1 g/mol and 16 g/mol respectively.
What is the empirical formula of the compound C H N?
The empirical formula of the compound is: An organic compound containing C, H and N gave the following analysis C = 4 0 \%, H = 1 3. 3 3 \%, N = 4 6. 6 7 \%. Its empirical formula would be: The percentage of C, H and N in an organic compound are 4 0 \%, 1 3. 3 \% and 4 6. 7 \% respectively. The empirical formula is:
What is the empirical formula of formaldehyde?
Formaldehyde consists of 40.0\% carbon, 6.7\% hydrogen, and 53.3\% oxygen. What is its empirical formula? The empirical formula is CH2O. Assume that you have 100 g of formaldehyde. Then you have 40.0 g of C, 6.7 g of H, and 53.3 g of O. Our job is to calculate the ratio of the moles of each element.
