2-A gas sample is found to contain 39.10% carbon, 7.67% hydrogen, 26.11%
aleksandrvk [35]

The molecular formula :

C₆H₁₄O₃PF

<h3>Further explanation</h3>

Given

39.10% carbon, 7.67% hydrogen, 26.11%  oxygen, 16.82% phosphorus, and 10.30% fluorine.

Required

The molecular formula

Solution

mol ratio :

C = 39.1 : 12 = 3.258

H = 7.67 : 1 = 7.67

O = 26.11 : 16 = 1.632

P = 16.82 : 31 = 0.543

F = 10.3 : 19 = 0.542

Divide by 0.542

C = 6

H : 14

O = 3

P = 1

F = 1

The empirical formula :

C₆H₁₄O₃PF

(The empirical formula)n = the molecular formula

(C₆H₁₄O₃PF)=184.1

(6.12+14.1+3.16+31+19)n=184.1

(184)n=184.1

n = 1

evablogger [386]
<h3>Answer:</h3>

C6H12O6

Explanation:

To find empirical formular you write out the element

Carbon Hydrogen Oxygen

3.96 769 5.28

then u althrough divide by their atomic numbers

3.96÷ 12 769÷1 5.28÷16

=0.33 =769 =0.33

also divide althrough by the lowest number

the lowest number is 0.33 so we use it to divide

0.33÷0.33. 769÷0.33. 0.33÷0.33

= 1 = 2 = 1

empirical formular= CH2O

To find the Molecular formular

Molecular number = molar mass

(CH2O)n = 182

(12+1×2+16)n = 182

30n = 182

n = 6

therefore the Molecular formular is C6H12O6
