Answer to Question #330734 in General Chemistry for Easy

Question

Butanol is composed of carbon, hydrogen, and oxygen. If 1.0 mol of butanol contains 6.0 x 1024 atoms of hydrogen, what is the subscript for the hydrogen atom in C4Hx Санхор

Answer 1

The subscript for the hydrogen atom in butanol is 10. So, the chemical formula is C₄H₁₀O

Assume the subscript for Hydrogen is X,

then, the formula for butanol is C₄H_xO.

Given here,

Number of atoms in one mole of butanol = 6.0 × 10²⁴ 

1 mole mole of Butanol contains 6.02 × 10²³.

Thus x=10

$$x= {6,0*10^{24} \over 6,02*10^{23}}$$
