Answer: The empirical formula is H2SO4 only.
Explanation: Because it is the simplest ratio of atoms of elements in a compound.
Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.

Answer:
The answer to your question is 0.1595 mg of Oxygen
Explanation:
Data
K = 38.67 g
N = 13.86 g
O = ?
Mass of oxygen in 336 mg
Process
1.- Convert 336 mg to grams
1000 mg ----------------- 1 g
336 mg ---------------- x
x = (336 x 1)/1000
x = 0.336 g of sample
2.- Calculate the mass of oxygen in 100g
Mass of oxygen = 100g - 38.67g - 13.86g
= 47.47 g
This means that oxygen represents 47.47% of the sample
3.- Calculate the grams of Oxygen in 0.336 mg.
Mass of Oxygen = (0.336)(0.4747)
Mass of Oxygen = 0.1595 mg
Dehydration means (removal of water molecule) and in this case a double bond is formed by removal of H and OH from two vicinal (neighboring) carbons, this occurs by protonation then lose of water molecule then lose of H⁺ (we have to add H⁺ from acid at the beginning due to OH⁻ is bad leaving group)

Answer:
Dalton based his theory on two laws: the law of conservation of mass and the law of constant composition. The law of conservation of mass says that matter is not created or destroyed in a closed system.
