A 2.500g sample of compound containing only Carbon and Hydrogen is found containing 2.002g of Carbon. Determine the empirical formula of the compound.

The empirical formula : CH₃

Given

2.5 g sample

2.002 g Carbon

Required

The empirical formula

Solution

Mass of Hydrogen :

= 2.5 - 2.002

= 0.498

Mol ratio C : H :

C : 2.002/12 = 0.167

H : 0.498/1 = 0.498

Divide by 0.167 :

C : H = 1 : 3

a sequence is a function whose domain is the set of natural numbers.

natural numbers are all the negative and positive integers

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
