What is the percent composition of carbon in heptane c7h16
Gnom [1K]

Answer: the percent composition of carbon in heptane is 83.9%

Explanation:

<u>1) Atomic masses of the atoms:</u>

  • C: 12.01 g/mol
  • H: 1.008 g/mol

<u>2) Molar mass of heptane:</u>

  • C₇H₁₆: 7 × 12.01 g/mol + 16×1.008 g/mol = 100.2 g/mol

<u>3) Mass of carbon in one mole of heptane:</u>

  • C₇: 7 × 12.01 g/mol = 84.07 g/mol

<u>3) Percent composition of carbon:</u>

  • % = (mass in grams of C) / (mass in grams of C₇H₁₆) × 100 =

           = (84.07 g/ 100.2 g) × 100 = 83.9% ← answer

Given that hclo4 is a strong acid, how would you classify the basicity of clo−4?
Mandarinka [93]
As a conjugate base of a strong acid,ClO4-would be classified as having a negligible basicity. The basicity of a chemical species is normally expressed by the acidity of the conjugate acid. The basicity of an acid is the number of hydrogen ions, which can be produced by one molecule of the acid.
