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

Given the balanced equation: 2KClO₃ ---> 2KCl + 3O₂ How many moles of O₂ are produced when 4.0 moles of KCl are produced?
Verizon [17]

Answer:

The answer to your question is 6.0 moles of O₂

Explanation:

Data

                      2KClO₃    ⇒     2KCl    +    3O₂

moles of O₂ = ?

moles of KCl = 4

Process

To find the number of moles of O₂, use proportions and cross multiplication.

Use the coefficients of the balanced equation.

                    2 moles of KCl ----------------- 3 moles of O₂

                    4 moles of KCl -----------------  x

                          x = (4 x 3) / 2

-Simplification

                          x = 12/2

-Result

                        x = 6 moles of O₂

-Conclusion

When 4,0 moles of KCl are produced, 6.0 moles of O₂ will be produced.
