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

Dustin is mixing concrete. A formula for concrete calls for 3/8 gal of water. Dustin wants to make 7/9 more concrete than the fo
slava [35]
We can use a ratio to solve this question. Lets refer to the amount formed by the formula as a serving
1 serving needs 3/8 gal
We want to create 7/9 servings extra, so
1 + 7/9 = 16/7
1 : 3/8
16/7 : x
1/(3/8) = (16/7) / x
8 / 3 = 16x / 7
x = 7/6
He needs to use 7/6 gallons of water.
