On analysis ,a saturated hydrocarbon is found to contain 83.70% carbon...
The empirical formula of a saturated hydrocarbon containing 83.70% carbon and 16.30% hydrogen is C3H8.
Explanation:
To determine the empirical formula of a compound, we need to calculate the ratio of the number of atoms of each element present in the compound.
Step 1: Calculate the number of moles of carbon and hydrogen:
Assume we have 100g of the compound.
- The percentage of carbon is 83.70%.
- The percentage of hydrogen is 16.30%.
Using the atomic weights of carbon (12) and hydrogen (1), we can calculate the number of moles:
- Carbon: (83.70g / 12g/mol) = 6.975 moles
- Hydrogen: (16.30g / 1g/mol) = 16.30 moles
Step 2: Find the simplest whole number ratio:
Now, we need to find the simplest whole number ratio of carbon to hydrogen. Divide the number of moles of each element by the smallest number of moles.
- Carbon: 6.975 moles / 6.975 moles = 1
- Hydrogen: 16.30 moles / 6.975 moles = 2.34
The ratio of carbon to hydrogen is approximately 1:2.34.
Step 3: Determine the empirical formula:
To simplify the ratio, we multiply both numbers by a factor that will make the hydrogen number a whole number. In this case, we can multiply both numbers by 2 to get a whole number ratio.
- Carbon: 1 * 2 = 2
- Hydrogen: 2.34 * 2 = 4.68
The simplified ratio is 2:4.68, which can be approximated to 1:2.34.
The empirical formula is therefore C1H2.34. However, empirical formulas are always written with whole numbers only, so we need to multiply both subscripts by 2 to obtain the final empirical formula.
- Carbon: 1 * 2 = 2
- Hydrogen: 2.34 * 2 = 4.68
The final empirical formula is C3H8.
Therefore, the correct answer is option 'B' - C3H8.

- Carbon: 6.975 moles / 6.975 moles = 1
- Hydrogen: 16.30 moles / 6.975 moles = 2.34
The ratio of carbon to hydrogen is approximately 1:2.34.

- Hydrogen: 2.34 * 2 = 4.68
The final empirical formula is C3H8.
Therefore, the correct answer is option 'B' - C3H8.
