Answer:
Molecular formula = C₄F₈
Explanation:
Given data:
Empirical formula of compound = CF₂
Molar mass of compound = 200.4 g/mol
Molecular formula of compound = ?
Solution:
Formula:
Molecular formula = n ( empirical formula)
n = Molar mass of compound / empirical formula mass
empirical formula mass = CF₂ = 12+19×2 = 50 g/mol
n = 200.4 g/mol / 50 g/mol
n = 4
Molecular formula = n ( empirical formula)
Molecular formula = 4 ( CF₂)
Molecular formula = C₄F₈
You can tell if it's an Ion dipole if it is a force between ion and polar molecule. Just remember all these: an ion is an atom that gained or lost one or more electrons. It has negative or positive charge. A cation is positively charged. An anion is negatively charged. By knowing these, you can understand how they will bond together.
The number of grams of oxygen present in a sample of this compound that contains 40.00 grams of S = 29.9g of oxygen
<h3>Calculation of quantity of Oxygen</h3>
The compound contains the following:
sulphur = 57.20%
Oxygen= 100 - 57.20 = 42.80%
If 57.20% of the sample contains 40g of sulphur then 42.80% of the sample will contain X.
Make X the subject of formula,
X = 42.8 × 40/57.20
X= 1712/57.20
X= 29.9g of oxygen
