The answer is SeF6.
This is figured by:
2.231 grams of Se divided by 78.79 g/mol = 0.0283 moles of Se
3.221 grams of F divided by 18.998 g/mol = 0.1695 moles of F
0.1695 moles of Se/0.0283 moles of F = 5.9909 ~ 6 moles of Se/mole of F
So SeF6
Si2O3
An empirical formula is a chemical formula containing only the number of atoms why is formed (ex.: C6H12), without any indication about the structure.
The empirical formula would be SiO2. This is because the ratio of Si to O in the molecule is 1:2, which simplifies to SiO2.
To find the molecular formula from the empirical formula (C3H5O) and molar mass, you need to calculate the molar mass of the empirical formula. Then, divide the molar mass of the unknown compound by the molar mass of the empirical formula to get a ratio. Finally, multiply the subscripts in the empirical formula (C3H5O) by this ratio to determine the molecular formula of the unknown compound.
This molecular formula is C9H12.
Si2O3
The empirical formula of this compound would be MgO.
An empirical formula is a chemical formula containing only the number of atoms why is formed (ex.: C6H12), without any indication about the structure.
An empirical formula is a chemical formula containing only the number of atoms why is formed (ex.: C6H12), without any indication about the structure.
The empirical formula for the molecule containing 46% Si and 53.2% O is SiO2. This is derived by dividing the percentage composition by the respective atomic masses and simplifying to the nearest whole number ratio.
CH2O The empirical formula for carbohydrate showing the lead carbon. Organic chemistry in the study of compounds containing carbon
To find the empirical formula, we need to determine the molar ratio of chromium to silicon. If 73.52% of the compound's mass is chromium, then the mass of silicon must be 100% - 73.52% = 26.48%. Next, we convert these percentages to moles, then divide by the smallest number of moles to get the simplest whole number ratio. The empirical formula is CrSi.
The empirical formula for a molecule containing 46.8 percent si and 53.2 percent o is in the middle of the two. These added together and divided by two will net the average result.
The empirical formula would be SiO2. This is because the ratio of Si to O in the molecule is 1:2, which simplifies to SiO2.
Robert Boyle developed a definition of element in 1661 that made the concept subject to laboratory investigation, helping to move chemistry towards a more empirical science.
The empirical formula of the nitrogen oxide containing 53.85% nitrogen is N2O. This compound is commonly known as nitrous oxide or laughing gas, and it can act as a vasodilator to lower blood pressure when administered in controlled amounts.
The empirical formula for a substance containing 65.95% barium and 34.05% chlorine would be BaCl2 (barium chloride). This is determined by converting the mass percentage of each element to moles, finding the ratio of moles of each element, and simplifying to the simplest whole-number ratio.
