The picture represents sulfur trioxide.
which statement is true for one molecule of sulfur trioxide?
there are three atoms of sulfur and one atom of oxygen.
there are three atoms of sulfur and three atoms of oxygen.
there is one atom of sulfur and one atom of oxygen.
there is one atom of sulfur and three atoms of oxygen.
whats the answer

There is one atom of sulfur and three atoms of oxygen.

Explanation:

Sulphur trioxide is a covalent compound because sharing of electrons takes place between sulphur and oxygen. Both the elements are non-metals and hence, will form covalent bond.

The nomenclature of covalent compound is given by:

1. The less electronegative element is written first.

2. The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.

3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on.

Sulphur trioxide is and is a compound formed by one atom of sulphur and three atoms of oxygen in a fixed ratio by mass.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
