2 answers:
Answer: D. There is one atom of sulfur and three atoms of oxygen.
Explanation:
An atom is smallest unit of a matter or substance.It consist of three subatomic particles : electrons, protons, neutrons.
Element is a pure substance which is composed of atoms of similar elements. Example: Gold
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: water
1 molecule of is made up of one atom of sulfur and three oxygen atoms combined together in fixed ratio by mass.

According to the calculation, set I is both the most accurate and most precise.
Exactness is a quality or state of being precise. 2a: comparison accuracy sense: the degree of precision with which an action is carried out or a measurement expressed 2b. The novel was fact-checked for historical authenticity. 2a: conformance to truth, to a standard, or to a model: exactness It is impossible to estimate the number of casualties with accuracy. Let's calculate the precision for the fourth set, considering
Δ1 = ∣(8.41−8.56)∣ g=0.15 g
Δ2 = (8.72−8.56) g=0.16 g
Δ3 = ∣(8.55−8.56)∣ g=0.01 g
Therefore:
