Question

Molar mass of tetracarbon decahydride is:

A) 88 g/mol
B) 136 g/mol
C) 112 g/mol
D) 124 g/mol

Answer 1

The calculated molar mass of tetracarbon decahydride (butane) is approximately 58.14 g/mol. Here option A is correct.

The molar mass of tetracarbon decahydride, also known as butane (
`C_4H_1_0`), can be calculated by adding the atomic masses of its constituent elements. The molecular formula indicates four carbon atoms (C) and ten hydrogen atoms (H).

The molecular formula
`C_4H_1_0`, composed of four carbon atoms and ten hydrogen atoms, yields this molar mass when considering the atomic masses of carbon (12.01 g/mol) and hydrogen (1.01 g/mol).

Calculating the molar mass:

(4 × 12.01 g/mol) + (10 × 1.01 g/mol) = 48.04 g/mol + 10.10 g/mol = 58.14 g/mol.
