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

The amount of solvent increases, since the solvent is the one diluting the solution, the more you want your solution diluted, the more of solvent you'd use. :)
(3) the forward reaction rate is equal to the reverse reaction rate
hope this helps!
Explanation:
Most molecules survive for long periods of time at room temperature because at room temperature, they are stable. The room temperature is the temperature between 20-25°C where human beings are the most comfortable.
At the room temperature, most molecules are in their natural physical state without any reason to rearrange their bonds and a times be destroyed. The energy at room temperature is just perfect for bond stability.

Answer : The density of a sample is, 34.2 g/L
Explanation :
Density : It is defined as the mass contained per unit volume.
Formula used for density :
Given :
Mass of a sample = 7.412 grams
Volume =0.217 L
Now put all the given values in the above formula, we get the density of a sample.
Therefore, the density of a sample is, 34.2 g/L
