What is the percentage composition of propene?

Answer 1

Water - H2O

Find the atomic masses and add them together.

H: 1.00

H: 1.00

O: 16.0

------------

18.0 grams/mol

Take the atomic masses and divide it by the molecular mass to get % composition

Hydrogen: 2.00 ÷ 18.0 = 11.1%

Oxygen: 16.0 ÷ 18.0 = 88.9%

H2O contains 11.1% hydrogen and 88.9% oxygen

Answer 2

not sure exactly but the chemical formula is C2H6

Answer 3

The formula for propane is C3H8. This is a hydrocarbon and contains three carbon and eight hydrogen atoms.

Answer 4

Propene is C3H6.

Carbon: 85,62 %

Hydrogen: 14,38 %

Answer 5

C - 81.71179%

H - 18.28820%
