Explanation:
Given parameters:
Number of moles of the sulfur trioxide = 1.55kmol = 1.55 x 10³mole
Unknown:
Mass of the sulfur trioxide = ?
Solution:
To solve for the mass of the sample of sulfur trioxide:
- Find the molar mass of the compound i.e SO₃
atomic mass of S = 32g
O = 16g
molar mass = 32 + 3(16) = 80g/mol
mass of SO₃ = number of moles x molar mass
mass of SO₃ = 1.55 x 10³ x 80 = 124000g or 124kg

Plumbum. The latin word for liquid silver.
Answer:
Explanation:
Looking at the atom, you see that there is 1 carbon atom and 2 oxygen atoms.
The chemical formula of Carbon is just C (from the periodic table), and the chemical formula of Oxygen is just O (from the periodic table).
When you create the chemical formula of a compound, you want to indicate how many atoms of each element there are. Here, since there are 2 oxygen atoms, you want to have some form of 
, and since there's only 1 carbon atom, you want to have some form of C.
Now, we just put it together: (this is btw carbon dioxide)
