Which of the following formulas has the smallest percent
KiRa [710]

Answer: CF4

Explanation:

Calculate the molar mass of each compound. Divide the molar mass of Carbon by the molar mass of each compound, then multiply the answer by 100 to get the percentage.

CF4= 12+(19X 4)

=12+76= 88 g/mol

%C= 12/88 x 100= 13.64%

CO2= 12+(16 X 2)

12+32= 44 G/MOL

%C= 12/44 x 100= 27.3%

CH4= 12+ (1 X4)

=12+4

=16 G/MOL

%C= 12/16  X 100= 75%

C204

(12X2) + (16X4)

24+64

= 88 g/mol

%C= 24/88 x 100

= 27.3%
