What is the formula mass of 2-butene, #C_4H_8#?

Answer 1

#M_r(C_4H_8)=56#

#M_a(C) = 12# #M_a(H) = 1#
#M_r(C_4) = 12 * 4 = 48# #M_r(H_8) = 1 * 8 = 8#
#M_r(C_4H_8) = 48 + 8 = 56# #M_r(C_4H_8)=56#

Answer 2

The formula mass of 2-butene (C₄H₈) is calculated by adding the atomic masses of all the atoms in the molecule.

Carbon (C): 4 atoms × atomic mass of carbon = 4 × 12.01 = 48.04 g/mol Hydrogen (H): 8 atoms × atomic mass of hydrogen = 8 × 1.01 = 8.08 g/mol

Formula mass of C₄H₈ = 48.04 g/mol (for carbon) + 8.08 g/mol (for hydrogen) = 56.12 g/mol

Answer 3

To calculate the formula mass of 2-butene (C₄H₈), you sum the atomic masses of all the atoms in the molecule.

The atomic masses are:

  • Carbon (C): 12.01 grams per mole
  • Hydrogen (H): 1.008 grams per mole

There are four carbon atoms and eight hydrogen atoms in 2-butene.

Formula mass of 2-butene (C₄H₈) = (4 × atomic mass of carbon) + (8 × atomic mass of hydrogen) = (4 × 12.01) + (8 × 1.008) = 48.04 + 8.064 = 56.104 grams per mole

Therefore, the formula mass of 2-butene (C₄H₈) is approximately 56.104 grams per mole.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
